When light rays enter a rough medium like gases, the light rays get deflected in random directions. This is known as scattering of light. The light rays from Person A reaches mirror and gets reflected to reach Person B.

Likewise, the light rays from person B reaches the mirror and gets reflected to reach person A. This phenomenon is known as reflection of light.
If he moves couple of steps away from the mirror, what will happen to the image? The size of the image will be as same as the size of the object. Why is it so? It is written in mirror image so that the driver in the vehicle light shadow and reflection in front of the ambulance could read it correctly from his rear view mirror and he would make way for the ambulance to reach the hospital or patient as soon as possible.
You have to cast the shadow of your pencil on the wall with light shadow and reflection help of a candle in a dark room. How can you obtain the shadow of the same size, small size and big size of the same pencil?

It is called reflection of light. Which of the following would reflect the most light?
An object with a crumpled surface A smooth, shiny object with flat surfaces A rough object with curved surfaces A dark, shiny object with curved surfaces A smooth, shiny object with flat surfaces, such as a mirror, will reflect the most light 5.
Light shadow and reflection does an opaque material affect light? We can see through a translucent object but the vision would be faint.
CBSE NCERT Class 6 Physics Light Shadow and Reflection
An object which does not allows passage to light is called an opaque object. We cannot see through an opaque object. Transparent translucent Formation of Shadow When light falls on an opaque object, a dark patch is formed on the other side of the object; if a screen is present on the other side.
Three things are required for formation light shadow and reflection shadow, viz.
The size of shadow depends on the distance of source of light and on the angle at which the light rays fall on the object. If the source of light shadow and reflection is closer to the object, a larger shadow is formed than when the source of light is far from the object. If the angle of incident light is smaller, the shadow is longer.

On the other hand, if the angle of incident light is bigger, the shadow is smaller. This explains, why our shadows are longer in the morning and evening and smaller in the noon. Structure of a pinhole camera:
