Question: If the refractive index of a medium is greater than 1, what happens to the wavelength of light in that medium compared to its wavelength in vacuum?

Options:

  1. It increases
  2. It decreases
  3. It remains the same
  4. It becomes zero

Correct Answer: It decreases

Solution: 

The wavelength of light decreases in a medium with a refractive index greater than 1, as it is given by λ\' = λ/n.

Questions & Step-by-Step Solutions

If the refractive index of a medium is greater than 1, what happens to the wavelength of light in that medium compared to its wavelength in vacuum?
  • Step 1: Understand what refractive index means. It is a number that tells us how much light slows down in a medium compared to vacuum.
  • Step 2: Know that the refractive index (n) is always greater than 1 for any medium other than vacuum.
  • Step 3: Remember the formula for the wavelength of light in a medium: λ' = λ/n, where λ' is the wavelength in the medium, λ is the wavelength in vacuum, and n is the refractive index.
  • Step 4: Since n is greater than 1, when you divide λ by n, the result (λ') will be smaller than λ.
  • Step 5: Conclude that the wavelength of light decreases when it enters a medium with a refractive index greater than 1.
  • Refractive Index – The refractive index (n) of a medium indicates how much light slows down and changes wavelength when entering that medium compared to a vacuum.
  • Wavelength Change – The relationship between the wavelength of light in a vacuum (λ) and in a medium (λ') is inversely proportional to the refractive index (n), expressed as λ' = λ/n.
