When light rays hit a rough surface and bounce back at different angles?

When light rays hit a rough surface and bounce back at different angles?

For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection. Diffuse reflection is when light hits an object and reflects in lots of different directions. This happens when the surface is rough.

In which direction will a light ray falling along the normal to a mirror be reflected?

If the light approaches the mirror along the normal than it will reflect back in the same direction because both the angle of incidence and reflection are same because both of them lie in the 0 degree.

Is the image formed by a plane mirror exactly the same as an object?

Summary. A plane mirror always forms a virtual image (behind the mirror). The image and object are the same distance from a flat mirror, the image size is the same as the object size, and the image is upright.

What is a kaleidoscope state the principle on which it is based?

Actually the Kaleidoscope is based on the principle of multiple reflection. according to this the light ray get reflected by these multiple mirror. when a light ray falls on one mirror , then it get reflected to the another one.

What is Kaleidoscope state the principle on which it is best?

actually the Kaleidoscope is based on the principle of multiple reflection. according to this the light ray get reflected by these multiple mirror. when a light ray falls on one mirror , then it get reflected to the another one. and this phenomena gives a wonderful pattern.

What is the example of multiple reflection?

The best example of multiple reflection is KALEIDOSCOPE . In a kaleidoscope, beautiful patterns are formed due to multiple reflections. Multiple reflections are used in PERISCOPE. Periscopes are used in submarines, war tanks and by solders in bunkers to see objects that are not visible directly.

Which of the following device is based on multiple reflection?

Megaphone is based on multiple reflections of sound. It is shaped like a horn and amplified sound can be sent in a particular direction. Multiple reflections means the sound is reflected more than once and the repeated reflection that results in this persistence of sound is called reverberation.

How do I calculate multiple images?

The number of images formed by two adjacent plane mirrors depends on the angle between the mirror. If (in degrees) is angle between the plane mirrors then number of images are given by, n = 360 θ − 1. We verify this formula in this experiment.
