Question

what precautions do you while conducting the experiment to verify the relation between angle of incidence and angle of refraction​

Answer 1

Answer:

The relationship between the angle of incidence and angle of refraction is explained by Snell's law, which states that the ratio of the sine of the angle of refraction and the sine of the angle of incidence is always constant and equivalent to the ratio of phase velocities of the two mediums it is passing through.
