Answer:
1. 1, 2, 4 all show some form of refraction as the bending of a light ray when passing from one media to another.
Explanation:
Number 4 is the most accurate as it also shows some light being reflected and the bending of the refracted light ray in the correct direction for going from a medium of low refractive index (air) into a higher refractive index material (crown glass)
Now let’s say you’re on the Moon. If you were to drop a hammer and a feather from the same height, which would hit the ground first?
Trick Question! On the moon both objects would hit the ground at the same time. On Earth, the hammer lands first.
So yeah, the student is right. Galileo gave us this theory long ago.
The matter from the explosion can reach him, hitting him. He should be able to feel that.
