Refraction

Aim:
To investigate how light is affected by changing the substance it is traveling through
Method:
Collect the equipment from your teacher and set them up to produce a single mean of light
Equipment:
Ray box, power source, glass or perspex block, single-slit ray slide
(Angle of incidence)  (Angle of refraction)

Curved mirrors

Aim
To investiate the reflection of light rays in concave and convex mirrors.

Equipment
Ray box, triple-slit ray slide, concave and convex mirrors, power supply.

Method
1,)  Set up your ray box, triple-slit ray slide and power supply.
2.) Place the mirrors on your book as indicated below. Place the ray box at the top of the page and shine the rays of light at the mirror.
3.) Ensure that the middle ray of light is hitting the mirror at a 90 degree angle.
4.) Carefully trace the direction of the three incident rays and the three reflected rays.
