The relation between speed frequency and wavelength of a wave is:
- A
Speed = frequency * wavelength
- B
Speed * frequency= wavelength
- C
Speed =frequency/ wavelength
- D
Speed =frequency+ wavelength
Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known.
The correct answer is option A. It indicates correct relation between velocity, frequency and wavelength. As this is a formula hence only one option A is correct.
v = f λ. Frequency should be multiplied with wavelength not speed.
v = f λ. Frequency should be multiplied with wavelength not divided by it.
v = f λ. Frequency should be multiplied with wavelength not added.
