light-reflection and refraction

The incident ray, the reflected ray and the normal at the point of incidence all lie in the same plan..

Introduction - We see a variety of objects in the world around us. However, we are unable to see anything in a dark room. On lighting up the room, things become visible. That is, light is required to see things around us. Thus light can be defined as the external cause..

Introduction - It is a matter of common experience that the objects inside a dark room, which are invisible, become visible when the room is illuminated by a source of light. Thus light can be defined as the external cause responsible for the sensation of visio..

Reflection of Sound - When sound is incident on a solid or a liquid surfaceit bounces off the surface like light rays. Sound waves also obey the laws of reflection and refraction. For sound waves to reflect, we need extended surface or obstacle of l..

Scattering is a general physical process whereby some forms of radiation, such as light or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which it passes. A large number of molecules are ..

Characteristics of Light - Light is a form of energy produced by luminous objects. Light can travel through vacuum. Light can penetrate through transparent materials but cannot pass through opaque objects. Light travels in a straight line in an opti..

Question 1 - Question: Light is a form of energy produced by a ______. 1. luminous object 2. transparent object 3. non-luminous object 4. opaque object Answer:..

A ray of light refracts or deviates from its original path as it passes from one optical medium to another because the speed of light change..

The ray of light which travels into the second medium, when the incident ray strikes the surface of separation between the mediums 1 and 2, is called the refracted ra..

The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane. For any two given pair of mediums, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. The above law is call..
