For a wave propagating in a medium, identify the property that is independent of the others.
Options
(a) Velocity
(b) Wavelength
(c) Frequency
(d) All these depend on each other
Correct Answer:
Frequency
Explanation:
Velocity = frequency × wavelength
When light is travelling in a medium, ʋ is assumed to be the same and the velocity of light in the medium is less. λ gets adjusted so that (c’/λ’) = ʋ. Here ʋ is independent. It is frequency of light that is energy that is a constant. Wavelength and velocity change.
Therefore, c/λ = constant.
