Question

A beam of light travelling in water is incident on a glass which is immersed in the water. The incident beam makes an angle of 40° with the normal. Calculate the angle of refraction in the glass.

[Refractive index of water = 1.33, Refractive index of glass = 1.5]

[sin 40° = 0.6428, cos 40° = 0.7660, tan 40° = 0.8391]

Answer 1

A beam of light travelling in water is incident on a glass which is immersed in the water. The incident beam makes an angle of 40° with the normal. Calculate the angle of refraction in the glass.

[Refractive index of water = 1.33, Refractive index of glass = 1.5]

[sin 40° = 0.6428, cos 40° = 0.7660, tan 40° = 0.8391]
