Properties of light
-
-
-
-
Colours humans see are the light that is reflected of the object while the other colours are absorbed
-
Law of refraction
-
Light from air into perspex block, sintheta1/sintheta2 = n/1
Light from perspex block into air, sintheta2/sintheta1 = 1/n
Total internal reflection: when the light is travelling from a higher refractive index to a lower refractive index. And when the angle of incidence is greater than the critical angle
Critical angle: When angle of incidence is at a particular angle, the angle of refraction will be 90degrees
