When a wave enters a new medium at an angle, it bends, or refracts. is the bending of a wave as it enters a new medium at an angle other than 90 degrees. Refraction occurs because waves travel at different speeds in different mediums. ... You have probably noticed the refraction of light waves in water.

The correct answer to this is refraction. Light beams refract on the water in the air and create colors. This is basically how rainbows are made.
Answer:
He is wrong!
Explanation:
Frequency refers to how many wave lengths pass in a second and speed is how fast the wave is traveling for example the speed of light goes really fast but has a mid-level frequency.

I'm warning you before i answer this i'm not guaranteeing i'm going to answer this wright but I'm pretty sure its bill pushed a car for 5 minutes for 20-km while doing 15 J of work. Why I think this is the answer is because it directly tells you the most information giving you the time it took him to move the object that distance and also telling you how many joule's of force he's exerting (power).
Hope this helped :)
Answer:
20 meters per second
Explanation:
If an object accelerates for 2 seconds, and accelerates by 10 meters per second, then that objects speed will be 20 meters per second, assuming hat there are no other factors involved.
