Question

If wavelength is kept constant, which increases as the speed of a wave increases?1) period2) frequency3) amplitude4) phase

Answer 1

The formula for the speed of the wave is given as

`v=f*\lambda`

*Here f is the frequency

As from the given data, the wavelength is kept constant

From the above expression, it is clear that the speed of the wave is directly proportional to the frequency of the wave. As we increase the speed of the wave then the frequency also increases.

Hence, the correct option is (2)
