Question

How do you verify experimentally that sini/sinr is a constant​

Answer 1

Explanation:

Observation: If we calculate the ratio of the sine of angle of incidence and sine of angle of reflection than it will come out to be constant. Result: Ratio of sine of angle of incidence and angle of refraction is constant.

Answer 2

Answer:

Observation: If we calculate the ratio of the sine of angle of incidence and sine of angle of reflection than it will come out to be constant. Result: Ratio of sine of angle of incidence and angle of refraction is constant.

Explanation:

Procedure:

1. Take a wooden plank covered with white chart paper and draw two perpendicular lines passing through center as shown in figure.

2. Mark one line as NN which is perpendicular to the other line MM. Let O be the point of intersection of both lines.

3. Take protector and place it along NN and then mark the angles from 0o to 90o on both sides of NN as shown in figure.

4. Now place the semicircular glass disc such that the diameter coincides with the MM and center coincides with the O.
