Which wave has more energy? Why?
a
The blue wave has more energy because it has a longer wavelength.
b
The blue wave has more energy because it has a greater amplitude.
c
The red wave has more energy because it has a greater frequency.
d
The red wave has more energy because it has a greater height.
c. The red wave has more energy because it has a greater frequency.
Energy of a wave is directly proportional to its frequency, meaning the wave with higher frequency has more energy. Therefore, the red wave with higher frequency has more energy compared to the blue wave.
The correct answer is c: The red wave has more energy because it has a greater frequency.
The energy of a wave is directly proportional to its frequency. Higher frequency waves have more energy compared to lower frequency waves. The frequency of a wave is the number of complete cycles that occur in a given amount of time.
While wavelength and amplitude are important characteristics of a wave, they do not determine the energy of the wave. Wavelength is the distance between two corresponding points on a wave, and amplitude is the maximum displacement of a wave from its equilibrium position. These factors can affect the height and size of the wave, but not its energy.
