Why do light rays refract when they meet a new medium?
Light rays refract when they meet a new medium, travelling at a different velocity – the greater the change in the velocity, the more severe the bending of the ray against the normal. However, although the velocity changes, the frequency does not.
How is refraction of light related to angle of incidence?
The angle of incidence (formed by the ray of light travelling though air into a slab of rectangular perspex) is not directly proportional to the angle of refraction (angle formed between the ray travelling though perspex and the normal).
What is the critical angle of refraction in perspex?
∞ In perspex, at an angle of approximately 42, the angle of refraction is 90 (to the normal) which makes 42 the critical angle for perspex. Purpose: To investigate the behavior of light when it passes from air into an optically denser medium.
Why do light rays refract in perspex prisms?
4. Why did the rays of light refract in perspex? Light rays refract when they meet a new medium, travelling at a different velocity – the greater the change in the velocity, the more severe the bending of the ray against the normal. However, although the velocity changes, the frequency does not.
