In this blog we are going to learn about light reflection.But before that do you know what is reflection?
Reflection is the change in direction of a wave at an interface which makes it return to the original medium.this was discovered by a scientist.
Types of Reflection
there are two types of light Reflection specular reflection and diffuse reflection.
Regular reflection is one of the perfect, mirror-like reflection of light.
In this type of reflection the reflected rays are also parallel to each other.
Reflection in mirror, water surface and highly polished floors, are examples of regular reflections.
Mirror
Any smooth polished surface which can reflect most of the light incident on it is called mirror or reflecting surface
Incident ray
The ray of light which strikes the reflecting surface is called the incident ray.
AB is the incident ray
Point of incidence
The point on the reflecting surface at which a ray of light strikes is called the point of incidence. B is point of the incidence
Reflected ray
The ray of light which bounces back into the same medium after reflection from the reflecting surface is called the reflected ray.
The perpendicular drawn to the surface at the point of incidence is called the normal.
Angle of incidence
The angle which the incident ray makes with the normal at the point of incidence is called angle of incidence.
Angle of reflection
The angle which the reflected ray makes with the normal at the point of incidence is called the angle of reflection. .
Next time we will learn more about this concept.
