|
When the frequency of a wave increases, what happens to the wavelength?
|
|
The wavelength is not directly affected by the frequency of a wave.
|
|
|
The wavelength increases.
|
|
|
The wavelength decreases.
|
|
|
More specific information is needed to form a conclusion about the wavelength.
|
Explanation:
Detailed explanation-1: -From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
Detailed explanation-2: -Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength.
Detailed explanation-3: -Wave speed equals frequency*wavelength. So doubling the frequency must halve the wavelength in order for wave speed to remain the same.
