Question

When light goes from a denser to a rarer medium at a spherical surface, the refracted ray:

विकल्प

• Bends towards the normal

• Travels along the principal axis

• Bends away from the normal

• Does not change direction at all

Answer 1

When light goes from a denser to a rarer medium, the refracted ray bends away from the normal. For the same object distance, the image may shift differently because the refractive index contrast changes.
