Light is incident on a glass slab making an angle of `30^(@)` with the surface. If the speed of light in air is `3 xx 10^(8) m//s` and the refractive index of glass is 1.5, find:
(i)the angle of refraction.
(ii ) the speed of light in glass.

Explanation

To solve the problem step by step, we will address each part of the question systematically.

### Given Data:
- Angle of incidence with the surface, θ_surface = 30°
- Speed of light in air, c_air = 3 × 10^8 m/s
- Refractive index of glass, μ_glass = 1.5

### Part (i): Finding the Angle of Refraction
