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.
D. The red wave has more energy because it has a greater frequency. Energy of a wave is directly proportional to its frequency.
The correct answer is d. The red wave has more energy because it has a greater frequency.
Energy in waves is directly proportional to their frequency. The higher the frequency of a wave, the more energy it carries. Therefore, the red wave, which has a greater frequency, will have more energy compared to the blue wave. The height or amplitude of the wave does not determine its energy level, but rather the intensity or strength of the wave. Similarly, the wavelength does not indicate energy but rather the distance between two consecutive points in a wave.
