Light of wavelength `4500Å` in vacuum enters into a glass block of refractive index 1.5. What is the wavelength of light in the glass block?

Explanation

To find the wavelength of light in a glass block when the light enters from a vacuum, we can use the relationship between the refractive index and the wavelength of light. The relationship is given by the formula:

\[ \mu_1 \lambda_1 = \mu_2 \lambda_2 \]

Where:
- \(\mu_1\) is the refractive index of the first medium (vacuum),
