What is Total Internal Reflection
If the angle of incidence in denser medium is increased further (i > θc), then the incident ray of light will be totally reflected in…

What is Critical Angle
When ray of light passes from a denser medium to a rarer medium, then the refracted my is deviated away from the normal. As a…
Explain Refractive Index
For a particular pair of transparent medium and a. particular colour of light when ray of light refracts from one medium to another, then if…
Describe Laws of Refraction of Light
We have already noticed that in the figure AB is the incident ray, BC is the refracted ray and NBN’ is the normal drawn at…
Explain Refraction of Light
Look at figure 1, here two media, air and glass are shown. Coming from air medium following the path AB, light ray incidents at point…
What is Magnification?
When we see an image produced by a mirror or a lens, then it may be larger, smaller or equal in size with respect to…
Explain on Blind Turn on Hilly Roads
To drive safely is an utmost duty for all driven. Besides, it is more difficult to drive in bad weather like rainfall and fogs. Especially,…
Describe Uses of Mirror
We use different types of the mirror for different purposes. These are described some uses of the mirror: Plane mirror: We see our appearance by…
Common Phenomena of Formation of Images in Plane and Spherical Mirrors
1) Simple periscope: Periscope is used to see a distant object directly if there is an obstacle. A simple periscope is constructed using two plane…
Explain Images formed in Convex Mirror
Depending on the position of the object in a concave mirror, real or virtual images are formed. But a virtual image of an object is…
