The Law of Reflection- angle of incidence of a wave hitting a surface equals the angle
of reflection
normal- line perpendicular to a surface( that is, forms a 90 degrees angle with the surface)
incident ray - ray of light that arrives at a mirror or enters a substance
angle of incidence - angle between the incoming ray and the normal
angle of reflection - angle between the reflected ray and the normal
point of incidence - point where a light ray arrives at a mirror or enters a substance
mirror- a smooth surface that reflects light (reflections can be seen in it); especially, a
piece of glass coated with silver on the back; looking glass
Fibre optics - thin flexible tubing with an inner surface that reflects light: used in optical
devices
concave mirror- reflecting surface that is curved inwards like the inside of a bowl or a
spoon; thinner in the middle and thicker at the edges
A concave mirror produces images different from those that a plane mirror produces.
