Question

Which wave has more energy? Why?



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

Answer 1

D. The red wave has more energy because it has a greater frequency. Energy of a wave is directly proportional to its frequency.
