Question

A ray of light strikes a glass slab $(R.l=\mu )$ of finite thickness $t$. The emerging light is

• A. parallel to the incident ray
• B. perpendicular to the incident ray
• C. rotates by an angle $\left[t{\sin }^{-1}\left(\frac{1}{\mu }\right)\right]$
• D. totally internally reflected

Answer 1

The correct option is A parallel to the incident ray

The emerging ray will be parallel to the incident ray.
