3
Q
What is the law of reflection?
A
The angle incidence is equal to the angle of reflection.
4
Q
What way does light bend when it enters a medium of higher refractive index than the one it was previously in?
A
It bends towards the normal.
5
Q
What way does light bend when it enters a medium of lower refractive index than the one it was previously in?
A
It bends away from the medium.
6
Q
What happens when light is absorbed?
A
The energy from the light is transferred into the particles of the substance.
