A monochromatic light of wavelength 500 nm travelling in air strikes a glass surfaces. Calculate the wavelength, frequency and speed of refracted light. Take `mu_("glass") = 1.5`.

Explanation

To solve the problem, we need to calculate the wavelength, frequency, and speed of the refracted light when monochromatic light of wavelength 500 nm strikes a glass surface with a refractive index (μ) of 1.5.

### Step 1: Calculate the Frequency of the Incident Light
The frequency (f) of light can be calculated using the formula:
\[ f = \frac{c}{\lambda} \]
where:
- \( c \) = speed of light in air (approximately \( 3 \times 10^8 \) m/s)
- \( \lambda \) = wavelength of light in air (500 nm = \( 500 \times 10^{-9} \) m)
