Question

identifying absorption and transmission
read the scenarios and decide which type of interaction (absorption or transmission) took place between the wave and the object.
people are able to hear footsteps because the sound made by a foot hitting the floor travels through the air to reach their ears.
when light from the sun hits the sidewalk, the sidewalk becomes warmer.

Explanation:

In the first scenario, sound waves travel through air to reach ears, which is transmission. In the second scenario, the sidewalk absorbs light - energy from the sun and warms up, which is absorption.

Answer:

1. Transmission
2. Absorption
