What is a periscope and waht is its use?
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.

Can A Convex Mirror And Concave Lens Form A Real Image
state the laws of reflection
how to make a periscope??
what is dispersion ? please explain.

A visitor had left his spectacles behind. How would you know if he is long sighted or short sighted by examining the spectacles
how could i make model for human eye
function of electroscope
what is the difference between image and shadow??????????
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.
