Reflection is when the direction of a ray of light is changed by using an object. Mirrors are great reflectors as they reflect light rays really well. There are 3 types of mirrors. Plane mirrors, concave mirrors, and convex mirrors.
Plane mirrors are straight and have an imaginary line perpendicular to the mirror on a right angle. This line is called the normal. When the ray of light hits the mirror, the ray reflects off at the same angle. The ray that hits the mirror is called the incidence ray and the ray that reflects off the mirror is called the reflected ray. The angle of incidence is the same as the angle of reflection.
Concave mirrors are mirrors that are bend inwards. When a set of parallel rays hit the mirror. The reflected rays converge into a focus point. In this type of mirror, the reflected ray angle is not the same as the angle of the incidence ray. Examples of these types of mirrors are satellite mirrors. The radio waves hit the concave mirror on the satellite and they bounce off and converge into a focus point which is the antenna. The antenna then transmits information that is needed to be transmitted.
Convex mirrors are mirror that bend outwards. When a set of parallel lines hit the this mirror, the reflected rays diverge. The focus point is known to be at the back of this mirror. In this mirror also the angle of incidence is not the same as the angle of reflection. There are many examples of concave mirrors. Mirrors used on roads the see oncoming traffic from a turning point is an example of a convex mirror.
There are two types of reflectors. Regular reflectors, and diffuse reflectors. Regular reflectors reflect light rays in a regular way. This means that the angle of incidence is the same as the angle of reflection. Regular reflectors also have straight surface which enables them to reflect properly. Diffuse reflector on the other hand are reflectors that do not reflect light rays regularly. This means that the surfaces of reflection are rough and if incidence rays hit this particular type of object, the reflected rays are scattered and are not reflected in a certain way.
