A ray of light passing through an equilateral triangular glass prism from air undergoes minimum deviation when angle of incidence is 34 of the angle of prism. The wall of a soap bubble is only as. Angle of incidence thi Angle of refraction thr Critical angle none Total internal reflection.
It discusses the difference between the law of reflection and refrac.
The speed of light through matter is less than it is in a vacuum because light interacts with atoms in a material. All forms of light travel at the same speed of 186000 miles per second 300000 km sec. This calculator computes the angle of refraction v using Snells law and the critical angle a c given above. When we talk about the speed of light were usually talking about the speed of light in a vacuum which is 300 x 10 8 ms.
