Question

absorption of sound waves
echoes as reflections
its probably not a surprise when you see
your own reflection in a mirror, but did you
know you can hear your reflection too?

1. how is an echo like a reflection? use the

image to help you explain.
the echo is \bouncing\ off the rock
thingy and is causing it to reflect off and
go back to where it was caused from

Explanation:

Both an echo and a light reflection involve a wave bouncing off a surface and returning to its source. For the echo (sound wave), the image shows sound traveling from the person, bouncing off the distant canyon rock surface, and traveling back to the person to be heard. This matches how light (for a mirror reflection) bounces off a surface back to the viewer.

Answer:

An echo is like a reflection because both involve a wave (sound for echo, light for visual reflection) bouncing off a hard surface and traveling back to its original source. As shown in the image, the person's sound waves bounce off the canyon rock and return to them as an echo, just like light bounces off a mirror to show a visual reflection.
