Answer:
FIRST ONE
Explanation:
2. Record your observations about what happens to a wave when it reaches the boundary between two media.
the wave bounces back off the first media and returns to it origanal resting place
Explanation:
What happens in a landslide?
Water moves into an area where it does not belong.
Earth materials that are no longer held by friction move down a slope.
The upper region of a hill becomes built up by rocks.
Soil washes away into a stream.
(This is science)
What effect does heat have on a chemical reaction?
Answer:
Particles can only react when they collide. If you heat a substance, the particles move faster and so collide more frequently. That will speed up the rate of reaction. ... The rate of reaction will probably have doubled for that increase in temperature - in other words, an increase of about 100%.

What is the effect
A wave enters a new medium perpendicular to the boundary between the two media.
Answer:
something that is produced by an agency or cause; result; consequence: Exposure to the sun had the effect of toughening his skin. power to produce results; efficacy; force; influence: His protest had no effect.
Refraction is the change in direction of propagation of a wave when the wave passes from one medium into another, and changes its speed. Light waves are refracted when crossing the boundary from one transparent medium into another because the speed of light is different in different media.
