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.

Q1)
Use the following information to answer the next question.
Two plane mirrors, M1 and M2 are placed at a right angle. A ray of light is incident on M1 at P1and gets reflected from M1. It then gets reflected from M2 at P2.
If OP1 = OP2, then the angle of reflection of the ray at P2 will be

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.
