Verification of snells law of refraction

Label this diagram

a - light box

b - slit

c - normal

d - glass block

e - paper

f - angle of incidence

g - angle of refraction

Demonstrate the method of this experiment • 1

• Place glass block on paper and draw around it

• Shine light ray from light box

Demonstrate the method of this experiment • 2

• Draw two dots on each side of block to show the path of beam

• Remove block and connect both dots by a line

Demonstrate the method of this experiment • 3

• Draw normal

• Use a protractor to measure i and r

Demonstrate the method of this experiment • 4

• Repeat previous steps with a different angle each time

• Calculate sin i and sin r for each set

Define 2 precautions that are associated with this experiment • 1

Place block in the exact same spot each time

Define 2 precautions that are associated with this experiment • 2

To prevent error dont use small angles of i

Define the headings used to graph this experiment

• y - sin i

• x - sin r
