An electromagnetic radiation of frequency n, wavelength λ, travelling with velocity v in air, enters a glass slab of refractive index μ. The frequency, wavelength and velocity of light in the glass slab will be respectively (a) n, 2λ and v/μ (b) 2n/μ, (λ)/(μ) and v (c) n/μ, (λ)/(μ) and v/μ (d) n, (λ)/(μ) and v/μ

Answer: (d). Frequency depends only on the source: stays n. Speed becomes v/μ and wavelength (λ)/(μ). So the answer is (d) n, (λ)/(μ), v/μ.

Refraction, Glass Slab & Apparent Depth

An electromagnetic radiation of frequency $n$ , wavelength $\lambda$ , travelling with velocity $v$ in air, enters a glass slab of refractive index $\mu$ . The frequency, wavelength and velocity of light in the glass slab will be respectively

Show answer and solution

Answer: (d)

Frequency depends only on the source: stays $n$ .
Speed becomes $\frac{v}{\mu}$ and wavelength $\frac{\lambda}{\mu}$ .
So the answer is (d) $n,\ \frac{\lambda}{\mu},\ \frac{v}{\mu}$ .
