Since v = λ f, the speed v of a wave depends on its frequency f.
True or False?
It’s ++FALSE++, the reason is: speed of the wave depends on the properties of the medium. Example:
- for a mechanical wave, speed of wave depend on elastic and inertial properties of the medium
- for an electromagnetic wave, speed of wave depends on electrical and magnetic properties of the medium
while, frequency of waves depends on number of cycles set by the source. wavelength of wave is dependant on both frequency of wave and speed of the wave as per the formula λ =vf
