Homework Statement
under what condition is the angle of incidence greater than the angle
of refraction?and viseversa?
and WHY?
AND how come the speed of light slows down when it travels from a
less dense to a more dense substance?and vise versa?
Homework Equations
laws and principles of refraction and reflection
The Attempt at a Solution
i learned that When light ray enters a denser object, the ray bends and moves toward the normal and the angle of refraction is less than the angle of incidence.
but i still don't get WHY it is like that.
can anyone help me?
