Question

1. a wave with high amplitude ________. (1 point)

has a short period
has a short wavelength
has more energy than a wave with low amplitude
moves faster than a wave with low amplitude

Explanation:

• Period and wavelength: These are related to the frequency and speed of the wave (through the formula \(v = f\lambda\), where \(v\) is speed, \(f\) is frequency, and \(\lambda\) is wavelength). Amplitude has no direct relation to period or wavelength.
• Energy: The energy of a wave (such as in the case of a simple harmonic wave like a light wave or a sound wave) is proportional to the square of the amplitude (\(E\propto A^{2}\), where \(E\) is energy and \(A\) is amplitude). So a higher - amplitude wave has more energy.
• Speed: The speed of a wave (in a given medium) is determined by the properties of the medium (for example, the speed of light in a vacuum is \(c = 3\times10^{8}\ m/s\), and for mechanical waves like sound in air, it depends on temperature, pressure etc.). Amplitude does not affect the speed of the wave.

Answer:

has more energy than a wave with low amplitude
