Measurement of the refractive index of a liquid

Label this diagram

a - Second pin

b - Pin on bottom of tank

c - Image of pin

d - Glass tank of water

e - Apparent depth

f - Real Depth

Demonstrate the method of this experiment • 1

• Put water in tank

• Measure depth

Demonstrate the method of this experiment • 2

• Put pin at the bottom

• Image of pin appears to be higher than actual pin

Demonstrate the method of this experiment • 3

• Put second pin as deep as the image outside the tank

Demonstrate the method of this experiment • 4

• Measure apparent depth - distance from water surface to second pin

• Repeat previous steps using different depths

Demonstrate the method of this experiment • 5

• Calculate refractive index using depth formula

• Calculate the average of refractive index

Define a precaution that is associated with this experiment

Measure bottom of the water not bottom of the tank

Define the depth formula

n = real depth / apparent depth

Define the headings used to graph this experiment

• y - real depth - cm

• x - apparent depth - cm
