Which describes the reflection of a wave?
ultraviolet waves of energy are taken in by sunburned skin.
a glass of water acts as a prism, splitting sunlight into a rainbow on a table.
sound waves from a shout move back and forth between canyon walls.
the same behavior is observed with light and other waves, and by the bounce of a billiard ball off the bank of a table.

Sound waves from a shout move back and forth between canyon walls.

Explanation:

When waves are reflected from the given target then in that case the the energy is bounced back into the same direction from which it is incident upon the target

So here in case of reflection of wave the energy is not absorbed by the surface but it is bounced back.

Also the energy is not transmitted from the given target

So here in this case the correct option must be

Sound waves from a shout move back and forth between canyon walls.

Since the waves are moving back and fourth between the walls then here we can say that energy is reflected back and fourth.

50 inches should be the resultant vector

real, smaller and upside-down.   so the answer should be b.
