Green light of wavelength 5460A˚5460 Å is incident on an airglass interface. If the refractive index of glass is 1.51.5, the wavelength of light in glass would be (c=3×108 ms−1)\left(\mathrm{c}=3 \times 10^{8} \mathrm{~ms}^{-1}\right)

Options

  1. A3640A˚3640 Å
  2. B5460A˚5460 Å
  3. C4861A˚4861 Å
  4. DNone of the above

Correct answer

A. 3640A˚3640 Å

Step-by-step solution

\mathrmaλg=λaμ=54601.5=3640A˚\mathrma^{\lambda} \mathrm{g}=\frac{\lambda_{\mathrm{a}}}{\mu}=\frac{5460}{1.5}=3640 Å
