Question

As the angle of incidence increases for light going from a denser medium to a rarer medium, the angle of refraction:

Options

• decreases

• first increases and then decreases

• also increases

• remains constant

Answer 1

For light going from a denser medium to a rarer medium, the angle of refraction is always larger than the angle of incidence. As the angle of incidence increases, the angle of refraction also increases until it reaches \[90^\circ\] at the critical angle.
