The greater the amplitude of a wave, the greater its
1 answer:
The greater the amplitude of a wave, the greater its D) energy
Explanation:
- The amplitude of a wave is the maximum displacement of the wave with respect to the equilibrium position. It is generally indicated with A.
The energy of a wave is proportional to the square of its amplitude:
Therefore, we immediately see that option D) is the correct one: the greater amplitude of the wave, the greater its energy.
The other quantities of a wave are:
- Frequency: it is the number of complete cycles of the wave per second
- Wavelength: it is the distance between two crests of the wave
- Speed: the speed of a wave is calculated using the equation
where f is the frequency and is the wavelength.
