Refraction of Light - Let us now see what happens when a ray of light is incident on the boundary separating the two media having different densities. A part of the light gets reflected and rest of the light changes its direction as it enters the second medium. The diagram shows how the l..

The following rays are usually considered while constructing ray diagrams: A ray of light incident on a plane mirror at 90 degree gets reflected from the mirror along the same path. A ray of light falling on a plane mirror at any angle gets reflected from the mirror such that the angl..

In order to get white light from the dispersed light the prisms are arranged as shown in the diagram. Recombination of the seven colours of the dispersed white light to get white light is known as recomposition of white lig..

If the object is moving from -3 to -1,then displacement = x f - x i = -1 - (-3) =..

Rutherford proposed that electrons revolve at high speed in circular orbits around the positively charged nucleus. But according to the electromagnetic theory, if a charged particle were accelerated around another charged particle then there would be a continuous radiation of energy. The loss of ..

Spherical Mirrors - A mirror whose polished, reflecting surface is a part of a hollow sphere of glass or plastic is called a spherical mirror. In a spherical mirror, one of the two curved surfaces is coated with a thin layer of silver followed by a coating of red lead oxide paint. Thus, one side of..

Question: Draw a diagram to show the motion of a body whose speed remains constant but velocity changes continuously. Answer: If a body moves along a circle with uniform speed, though the speed is constant its velocity changes continuously as the velocity of the body at any ..

Formation of Image by a Convex Lens - When an object is placed in front of a lens, light rays coming from the object fall on the lens and get refracted. The refracted rays produce an image at a point where they intersect or appear to intersect each other. The formation of images by lenses is usuall..

The following rays are considered while constructing ray diagrams for locating the images formed by a concave lens for various position of the object. An incident ray of light coming from the object parallel to the principal axis of a concave lens after refraction appears to come from..

Question: What is the value of q in the following diagram? 1. 30 o 2. 45 o 3. 90 o 4. 60 o Answer: ..
