reflection & refraction of light

Reflection is the phenomenon where the incident light falling on a surface is sent back to the same mediu..

Specular or regular reflection is the perfect, mirror-like reflection of light. In this type of reflection the reflected rays are also parallel to each other. Reflection in a mirror, a water surface and highly polished floors, are examples of r..

Irregular reflection or diffused reflection takes place when a ray of light is incident on a wall or wood, which is not smooth or polished. In this case, the different portions of the surface reflect the incident light in different directions. In such cases no def..

Reflection of Light - When a ray of light falls on any surface, a part of the light is sent back to the same medium. This phenomenon where the incident light falling on a surface is sent back to the same medium is known as reflection. There are two types of reflection ..

When a ray of light hits a surface, it bounces off or reflects and then reaches our eyes. This phenomenon by which a ray of light changes the direction of propagation when it strikes a boundary between different media through which it cannot pass is described as the reflection ..

According to the law of reflection of sound the directions in which the sound is incident and reflected make equal angles with the normal to the reflecting surface and the three lie in the same plan..

The reflection at any plane surface is found to obey the laws of reflection. The laws of reflection are: The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane. The angle of incidence is equal to the angle of ..

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 large size. For example, the rolling of thunder is du..
