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.

Explanation:
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.

how waves affect matter at the macroscopic and particle levels.
Describe one piece of evidence that the wave carries energy from one place to another.
Answer:
Without shifting matter the entire distance, waves can transfer energy over distance. For instance, without the water itself moving many kilometers, an ocean wave may move many kilometers. The stream, a motion known as a disruption, goes up and down. It is the disruption that flows in a wave, transferring power.
Explanation:
1. Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.
The motion of spring is similar to that of sound wave in that the direction of the particles of the medium is parallel to the direction of the wave.
Motion of springThe motion of a spring pushed forward and backward under goes simple harmonic motion that forms a sinusoidal path. In this type of motion, the direction of the particles of the medium is parallel to the motion of the wave.
Sound waveSound wave is mechanical wave in which the direction of the particles of the medium is parallel (longitudinal) to the motion of the sound wave.
Thus, motion of spring is similar to that of sound wave in that the direction of the particles of the medium is parallel to the direction of the wave.

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.

Whats the effect of this?
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.
Explanation:
havvee advvanncceed
Answer:
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. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.

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.
