incident rays and reflected rays and showing their direction

Sign Conventions and Rules for Drawing Ray Diagrams - These new cartesian sign conventions adopted during measurements are as follow..

Formation of Image by a Plane Mirror - Ray Diagrams - The following rays are usually considered while constructing ray diagram..

.e., CD line, then it is evident that as compared to the ray Y, ray Z has to travel a longer distance, equal to QRS in order to emerge out of the crystal. If the waves Y and Z are in phase after reflection, the difference in distance travelled by the two rays..

The 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 of ligh..

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..

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 ..

Reflection of Light by a Plane Surface - The figure shows how a ray of light is reflected by a plane surface. Let MM' represent a reflecting surface. When a ray of light is incident on MM' in the direction IO it gets ..

The figure shows how a ray of light is reflected by a plane surface. Let MM' represent a reflecting surface. When a ray of light is incident on MM' in the direction IO it gets reflected along the direction OR..

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..
