When a monochromatic light is incident on a surface separating two media, both the reflected and refracted lights have the same:
Show Hint
- Frequency
- Wavelength
- Velocity
Amplitude
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Reflection and Refraction of Light When a monochromatic light wave travels from one medium to another, it undergoes reflection and refraction at the interface.
Step 2: Property of Frequency in Different Media The frequency of light remains unchanged during reflection and refraction. This is because the frequency of a wave is determined by the source and is not affected by the medium through which it propagates.
Step 3: Effects on Other Parameters - The wavelength of light changes as it enters a new medium, because the velocity of light varies according to the refractive index of the medium. - The velocity of light also changes due to the medium's optical density. - The amplitude of light may change due to partial reflection and absorption at the interface. Thus, the correct answer is: \[ \mathbf{Frequency} \]
