Critical Angle for the diamond-air interface The Critical Angle for the diamond-air interface is 24 degrees. This means if the ray of light in the diamond medium strikes the separating surface between the diamond and air making an angle more than 24 degrees with the normal to the point of incidence then that ray of […]
The Critical Angle for the glass-air interface is 42 degrees. This means if the ray of light in the glass medium strikes the separating surface between glass and air making an angle more than 42 degrees with the normal to the point of incidence then that ray of light will undergo a total internal reflection […]

Snell’s Law comes into action in the case of refraction of light, which is the change in direction of a light ray as it goes from one medium to another. As shown in Figure, a ray of light that encounters a change in medium is partially reflected, as if the boundary were a mirror. The […]
In this post, we will just talk about some special features of prism that make it a suitable medium to test the refraction of light. Subtopics discussed: Glass Prism as a refracting medium – features, and angle of prism Glass Prism – features of prism that contribute refraction through it To discuss the features we […]
Compare Refraction through a rectangular parallel surfaced glass block and Refraction through a glass prism – a ray of light from the air when passes through a rectangular glass block with parallel surfaces then refraction happens twice – (1) when light enters from air to glass and (2) when it comes out of the glass […]
This post is going to explain the term Lateral Displacement of light which is related to the refraction of light. This phenomenon is observed when a ray of light gets refracted twice while passing from air to a parallel-sided glass block and then again to air. Lateral displacement of light due to refraction When refraction […]
This post is on the total internal reflection and critical angle. Let’s begin. What are the total internal reflection and critical angle? When a ray of light passes from denser to rarer medium, the refracted ray bends away from the normal. Hence, the angle of refraction is greater than the angle of incidence. Gradually if […]
Refractive Index Numericals class 10 & practice problems
Here you will find a list of materials with their Refractive Index or Absolute Refractive Index values. These are extracted from Refractive Index Table or chart. Refractive Index (µ) of Air is 1 Refractive Index (µ) of Vacuum is 1 Refractive Index (µ) of Water is 1.33 Refractive Index of Kerosene is 1.41 Refractive Index […]

Although light travels in straight lines in a transparent material, such as air, if it passes into a different material, such as water, it changes direction at the boundary between the two, i.e. it is bent. The bending of light when it passes from one material (called a medium) to another is called the refraction […]
Here is the list of characteristics of an image formed by a plane mirror.(i) The size of the image is the same as the size of the object. (ii) The distance of the object in front of the mirror is equal to the distance of the image behind the mirror. (iii) A virtual and erect […]
Refraction of light is a phenomenon where light bends while moving from one medium to another, right at the surface separating these two mediums. Because of this when a pencil is dipped in a glass of water, it seems to be bent just at the surface separating the water in the glass and the air […]
