Everything CCEA students need to know about investigating angles of incidence and refraction.

However, as the angle of incidence increases the refracted light will bend from a bigger initial angle, and so the angle of refraction will also be bigger. What apparatus is used in this practical?

The first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle ...

Refraction of light is the change in direction of light when it passes from one medium to another. So, it is important to know how the light refracts from one medium to another.

A mirror image is the result of light rays bounding off a reflective surface. Reflection and refraction are the two main aspects of geometric optics.

Ever wonder how a mirror works? If you want to find the path that light takes when reflecting off a surface, you could use Fermat's Principle. This states something like this: The path that light ...
