Question

If the frequency is doubled, what effect will this have on the wavelength?

a. It will remain the same.
b. It doubles.
c. It increases by a factor of 1.54.
d. It is halved.

Answer 1

When the frequency of a wave is doubled, the wavelength will be halved for electromagnetic waves and doubled for sound waves.

Step-by-step explanation:

When the frequency of a wave is doubled, the effect on the wavelength depends on the type of wave. For electromagnetic waves, such as light, the wavelength is inversely proportional to the frequency, according to the equation: wavelength = speed of light / frequency. Therefore, if the frequency doubles, the wavelength will be halved, resulting in option d. It is halved. On the other hand, for sound waves, the wavelength is directly proportional to the frequency. So if the frequency doubles, the wavelength will also double.
