incident ray
the ray that comes from an object and strikes a surface.
reflected ray
the light ray that bounces off a surface
angle of incidence
the angle between the incident ray and the normal
angle of reflection
The angle between the reflected ray and the normal
normal
A line drawn at 90° to a surface, at the point of incidence
reflection
The bouncing back of a wave when it hits a surface through which it cannot pass.
plane mirror
a mirror with a flat surface
image
a copy of an object formed by reflected or refracted rays of light
image in a plane mirror
same size
same way up
back to front
refraction
a wave changing direction as it passes from one material to another
refraction diagram: less dense to more dense
light ray bends towards the normal
refraction diagram: more dense to less dense
light ray bends away from the normal
dispersion
white light separates into colours due to refraction through a prism
prism
a glass block, usually triangular, that causes dispersion by diffraction
