DIFFERENCE BETWEEN REGULAR AND IRREGULAR REFLECTION?
answer me fast.................
If light falls perpendicularly on a plane mirror, what will be the angle in which it will be reflected?
Options : 45o, 90o, 180o, 360o
(Please note that angle of reflection is not what is being asked.)

WHAT IS MULTIPLE REFLECTION
Light travels in a straight line and the phenomena is known as rectilinear propogation of light. There are many natural phenomena that occur due to this property of light, such as occurence of day and night.1) find out such applications natural as well as those commonly seen .2.) information about their way of occurance.3.) know the various usage of this property of light.

How to find the number of images formed between 2 mirrors placed at a certan angle ? Example ?
The image formed on the retina persists for aboutof a second. This means that if you are shown still pictures of a moving object at a rate faster than 16 seconds, then the object will appear to be moving. This is because, the image of a picture stays on your retina for of a second and you will not be able to recognize the time taken to change these pictures.
