Question

Which wave has more energy? Why?



a
The blue wave has more energy because it has a greater amplitude.
b
The red wave has more energy because it has a greater frequency.
c
The blue wave has more energy because it has a longer wavelength.
d
The red wave has more energy because it has a greater height.

Answer 1

b
The red wave has more energy because it has a greater frequency.

Energy in a wave is directly proportional to its frequency, meaning the higher the frequency, the higher the energy of the wave.
