Question

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

Options

• Passes undeviated along the normal only

• Bends away from the normal

• Reflects back into the rarer medium

• Bends towards the normal

Answer 1

When light goes from a rarer to a denser medium, the refracted ray bends towards the normal. The image position then depends on the curvature of the spherical surface and the object location.
