Compare and contrast surface waves with transverse waves and with longitudinal waves.
Answer:
Explanation:
In longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction (respectively) relative to the direction of energy transport. In a surface wave, it is only the particles at the surface of the medium that undergo the circular motion.
Surface waves are a combination of transverse and longitudinal waves that move along the surface of a medium, while transverse waves involve vibrations perpendicular to the direction of wave propagation, and longitudinal waves involve vibrations parallel to the direction of wave propagation.
What are surface, transverse and longitudinal waves?Surface waves are a type of wave that travels along the surface of a medium. They are characterized by having both a transverse and longitudinal component, meaning that the particles in the medium oscillate both horizontally and vertically as the wave travels. Examples of surface waves include ocean waves, seismic waves, and electromagnetic waves.
Transverse waves are a type of wave that involves vibrations perpendicular to the direction of wave propagation. In a transverse wave, the particles in the medium oscillate in a direction that is perpendicular to the direction the wave is moving. Examples of transverse waves include electromagnetic waves such as light and radio waves, and mechanical waves such as ripples on the surface of water.
Longitudinal waves are a type of wave that involves vibrations parallel to the direction of wave propagation. In a longitudinal wave, the particles in the medium oscillate in a direction that is parallel to the direction the wave is moving. Examples of longitudinal waves include sound waves, seismic waves, and longitudinal electromagnetic waves.

1. Pick an example of a wave. Describe one piece of evidence that the wave carries energy from one place to another.
Answer:
mass
Explanation:
1. Express the wave speed of each wave described below in meters per second.
A wave travels through a 2 meter rope in 1 second.
Answer:
In this instance, the sound wave travels 340 meters in 1 second, so the speed of the wave is 340 m/s. Remember, when there is a reflection, the wave doubles its distance. In other words, the distance traveled by the sound wave in 1 second is equivalent to the 170 meters down to the canyon wall plus the 170 meters back from the canyon wall.
Explanation:
Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, in below given ways, speed of each wave can be expressed.
What is electromagnetic wave?Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.
There is a relation between energy of wave. frequency of wave, and wavelength of wave
Mathematically,
E=hc/λ
where,
E = energy of electromagnetic wave
h is planks constant having value 6.67×10⁻³⁴js
c is speed of light that is 3×10⁸m/s
λ is the wavelength of electromagnetic wave
The sound wave moves 340 meters in one second, hence its speed is 340 m/s. In the event of a reflection, the wave's distance doubles. The distance covered by sound wave in one second is comparable to 170 metres down to a canyon wall + 170 meters back.
Therefore, in above given ways, speed of each wave can be expressed.

What is convection?
a Transfer of heat through objects touching the source
b Transfer of heat through direct physical contact
c Transfer of heat through electromagnetic waves
d Transfer of heat through the movement of particles
Answer:
d transfer of heat through the movement of particles
The correct answer is option d: Transfer of heat through the movement of particles. Convection is a mode of heat transfer that occurs through the movement of particles.
Convection is the transfer of heat through the movement of particles in a fluid, such as a gas or liquid. Option (d) is the correct answer. Convection occurs when a temperature difference exists within the fluid, causing the hotter particles to become less dense and rise while the cooler particles sink. This movement creates a circulation pattern known as convection currents. Convection is a significant mechanism for heat transfer in various natural and man-made systems. For example, when a pot of water is heated on a stove, the bottom of the pot gets hot, causing the water near the bottom to heat up and expand. This hot water rises to the top, transferring heat to the surrounding cooler water. As a result, the water circulates in a convection current, leading to a more uniform distribution of heat. Convection is also responsible for phenomena like ocean currents, atmospheric circulation, and even the formation of thunderstorms. It plays a crucial role in distributing heat within the Earth's atmosphere and oceans, impacting weather patterns and climate.

Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.

Hi, Im new! But, why is physical and chemical changes are different?
Answer:
Physical and chemical changes are different because one deals with changes to ones shape or form, while chemical is changing one substance to another.
Explanation:
A example of a physical change would be cutting a block of wood into a cube of would, its physical change changes from a block to a cube. A chemical change is changing the substance into another substance so for example, burning that cube of wood in a fire. The fire is burning the wood into ash meaning it's no longer wood but ash.

do you think the reflected waves would ever return to the airplane that transmitted them? explain
The reflected waves should not return back to the transmitted source if there no hindrances in the moving trajectories. If there is any hindrance or objections in front of the reflected wave there may occur some directional change and does not return to the airplane.
What is reflection?Reflection is phenomenon by which an incident wave on an object return backs in the straight direction. Reflection make an object shiny as we see from a mirror.
When light passes through a transparent or translucent material it penetrates through it and will refract or scatter from the object. This will happen when the frequency of the incident light does not matches with the frequency of the incident light.
If the a some waves are transmitted from an airplane and they are reflected in a straight direction, it will not revert back to the airplane because the reflected light will moves in a straight direction back from airplane.

A wave enters a medium where its wave speed is slower.
Answer:
Wave speed, frequency and wavelength in refraction
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Waves. Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light.

The amplitude of a wave is related to the energy of a wave. How could you demonstrate this relationship between energy and wave
Answer:
People holding the slinky supply the energy to make the patterns. To make pattern 1, people have to shake the slinky back and forth at a certain speed. To make pattern 2, the slinky has to be moved back and forth faster (higher frequency). To make pattern 4, the people need to move the slinky back and forth much faster. It is much easier to make pattern 1 than pattern 4 because it takes less energy. This illustrates the relationship between frequency and energy – the higher the frequency, the higher the energy.
