light
The characteristics of an image formed in a plane mirror/shadow/ afterimage
virtual( cannot be captured on a screen)
upright
laterally inverted
same distance as the object from the mirror
same size as the object
Properties of light
light travels in a straight line
light is a form of energy
Light can be refracted and reflected
The laws of reflection of light
The incident ray, the reflected ray and the normal must lie on the same place
and finally, the angle of incidence is equal to the angle on reflection
reflection of light
reflection of light is the bouncing of light rays of a hard surface
Refraction
refraction is the bending of light when it travels through different transparent media
The laws of refraction
the incident ray, the reflected ray and the normal must lie on the same plane
low density to high density bend towards normal
high density to low density bend away from the normal
LIGHT TRAVELS at a speed of 3 times 10tothepowerof8 m/s in vaccum
the speed of light in the denser medium is slower than that of the lless dense medium
