Question

Fill in the blanks:

When a ray of light travels from an optically less denser medium to an optically more denser medium, the angle of incidence is always _____ than angle of refraction.

• A. more
• B. less
• C. same as
• D. cant say

Answer 1

The correct option is A more

When a ray of light travels from an optically less denser medium to an optically more denser medium, the angle of incidence is always more than angle of refraction.
When light travels from rarer to denser medium, it bends towards the normal since refractive index of denser medium is more than the rarer. According to Snell's Law $\frac{sini}{sinr}=\frac{n_2}{n_1}$
