DIFFERENCE BETWEEN REGULAR AND IRREGULAR REFLECTION?
answer me fast.................
What is lateral inversion
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.)

If The Plane Mirror Is Rotated Through An Theta Then The Reflected Ray Turns Through An Angle Of 2 Theta
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.

pls experts fast
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.
