Verifying Snell's Law
Turn on the ray box and aim the light ray towards the glass block so that it makes an angle with the nearest surface of the block as shown in the picture. For each piece of paper, change the angle of the incoming ray.
i)The apparatus required for proving Shell's law are: glass prism,protracter (for measuring the angle ). The ratio of angle of incidence and and and angle of refraction is constant for given pair of media. The main aim of smells law is to give the value of refractive index.
