Question 25 • AZ-Earth and Space Science A (SC301)

How does the energy of a wave relate to the wave’s amplitude?

Answer
A
The more energy a wave has, the smaller the amplitude is. This is because they do not have a direct relationship.
B
The more energy a wave has, the larger the amplitude is. This is because they do not have a direct relationship.
C
The more energy a wave has, the smaller the amplitude is. This is because they have a direct relationship.
D
The more energy a wave has, the larger the amplitude is. This is because they have a direct relationship.

Explanation

A wave with a greater amplitude carries more energy, so energy and amplitude have a direct relationship. For many waves, the energy is proportional to the square of the amplitude, meaning increasing amplitude increases energy. Therefore, the correct choice is “The more energy a wave has, the larger the amplitude is.”
