Science: Refraction of light

Hello! This last week of Term 2 in Hurumanu 5, we did an experiment about how refraction light works. Refraction light is like where it sorts of zoomed up when in water like for example for the straw. It sort of bends in two when it's viewed in a glass filled with water.

Investigating Refraction - Bending Light

Aim: To investigate how light is affected by changing the substance it is traveling through.

Equipment: Ray box, power source, glass or perspex block, single-slit ray slide.

Method:

1) Collect the equipment from your teacher, and set them up to produce a single beam of light.
2) Place the glass block in the shaded area below
3) PLace the ray box at the top of the page and shine the beam so it travels along the 10° line to the centre of the protractor (this is your angle of incidence, °i).

Results:

Part A: Going from Air to Glass

Angle of Incidence (i°)	Angle of Refraction (r°)
10°	7°
20 °	15°
30°	20°
40°	25°

Part B: Going from Glass to Air

Angle of Incidence (i°)	Angle of Refraction (r°)
10°	8°
20 °	12°
30°	20°
40°	25°

Bye! Have a great day everyone!
