Question

When light passes from one medium to another, the characteristics that remains constant is?

Answer 1

Answer: Frequency is the characteristic of the source while wavelength is thecharacteristic of the medium. When monochromatic light travels from one medium to another, its speed changes, so its wavelength (λ=c/v) changes but frequency vremains unchanged.

Answer 2

When light passes from one medium to another, the characteristic that remains constant is its frequency.

• The frequency is the characteristic of light that always remains constant.
• While light is traveling from one medium to another, even though there is some variation in its speed as well as wavelength, there is no change in the frequency.
• It is so because the wavelength and speed of light depend on the medium through which it is traversing. While the frequency of the light doesn't depend on the medium.
• Thus, the correct answer will be frequency.
