Refraction of Light Through a Prism

A prism has

• 3 rectangular and 2 triangular surfaces

• 6 triangular surfaces

• 1 rectangular and 4 triangular surfaces

• 2 rectangular and 3 triangular surfaces

A glass prism used in air bends the light:

• away from base of prism

• towards base of prism

• towards angle of prism

• none of these

The angle between the emergent ray and the incident ray is known as the angle of _______.

• refraction

• deviation

• incidence

• emergence

Angle of deviation of a prism does not depend upon:

• Angle of prism

• Size of the prism

• Color of the light used

• Material of the prism

The angle of minimum deviation for a prism occurs when

• the angle of incidence is zero

• the angle of emergence is zero

• the angle of deviation is zero

• the angle of incidence is equal to the angle of emergence

Which of the following is true?

• Lower refractive index of prism will have greater bending of light

• Higher refractive index of prism will have higher bending light

• Bending of light does not depend on refractive index of prism

Which color of light bends the most when passing through a prism?

• Red

• Violet

• Blue

• Yellow

Angle of minimum deviation =

• 2i - Angle of prism

• (i₁ + i₂) - Angle of prism

• 2i + Angle of prism

• (i₁ + i₂) + Angle of prism

Angle of deviation of a prism is:

• (i₁ - i₂) + (r₁ - r₂)

• (i₁ + i₂) - (r₁ + r₂)

• (i₁ + r₁) - (i₂ + r₂)

• (i₁ - r₁) - (i₂ - r₂)
