With mirrors you would see- and we're going to And you may haveĪlready noticed this if you've played around a lot This the reflected ray, after it is kind ofīounced off of the surface. So then it'll hit the surface,Īnd then it'll bounce off, and it'll go just like that. That it bounces off at essentially the same angle,īut in the other direction. Ray because it's the ray as it approaches Terminology right, this light ray coming in, Is kind of what we normally associate with reflection Is doing one or the other, or something in between. Two types of reflection, and everything that reflects I think most of us haveĪ sense of what this is, but we'll try to get a littleīit more exact about it. Going to try to learn a little bit about reflection. Apart from catering students preparing for JEE Mains and NEET, PW also provides study material for each state board like Uttar Pradesh, Bihar, and others.In our eyes there are microscopic tiny sensors which are sensitive to light.They have 3 colors red,blue and green.If you look at a very bright thing such as the sun and close your eyes immediately you will see red.This means that red is the most sensitive to light.When you see any light source glowing brightly and when you see it and close your eyes immediately you will see green.In your case you might have seen a brightly glowing bulb.So green is less sensitive to light than red.Finally if you see a light source glowing dimly you will see blue color.So blue is least sensitive to light.One interesting fact for you that when you look at the sun immediately and close your eyes firstly you will see red color.But as the light intensity seen by our eyes decreases you will see green color then and finally you will see blue color and then you will see only black.The order of sensitivity of the receptors are: Physics Wallah strives to develop a comprehensive pedagogical structure for students, where they get a state-of-the-art learning experience with study material and resources.

In the above figure, ∠BON is the angle of reflection.

The angle between the reflected ray and normal to the surface is called the angle of reflection. The angle formed by a reflected ray and a perpendicular to the surface at the point of reflection. In the above figure, ∠AON is the angle of incidence. The angle between the incident ray and the normal to the surface is called angle of incidence.

The angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called thenormal. The ray of light which is turned back after reflection into the same medium in which the incident light is travelling is called the reflected ray. The perpendicular drawn to the reflecting surface at the point of incidence is called normal. In below figure ‘O’ is the point of incidence.

i.e., the point at which the incident ray falls on the reflecting surface. The point of incidence is that point at which light is incident on the reflecting surface. In the below figure ‘AO’ is the incident ray. The ray of light that strikes the surface is called the incident ray. Let us consider the reflection of light by a plane mirror as shown in the diagram.
