Question

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:

• For the first scenario: Sound waves travel through the air (a medium) to reach people's ears. Transmission occurs when waves pass through a medium.
• For the second scenario: When light (a form of energy) hits the sidewalk and the sidewalk becomes warmer, the sidewalk is absorbing the energy from the light waves.

Answer:

1. Transmission
2. Absorption
