HOW TO MAKE A PERISCOPE
why are cannot see our surrounding clearly when we enter a darkened cinema hall from bright sunshine but our vision improve after sometime.
Two plane mirrors PQ and QR are kept at right angles to each other. A ray of light AB is incident on the mirror PQ at an angle 30 degree. Draw the path of the reflected ray from the second mirror QR and find the angle of reflection for the mirror QR.
what is kaleidoscope ?
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.

plz aswer as soon as possible...
name the scientist who discovered that sunlight consists of seven colours.
state the laws of reflection
how to make a periscope??
Fill in the blanks
1.Periscope is based on the principle of successive -----------------from two plane mirrors.
2.The reflection taking place from the walls of a building is called --------------- reflection.
what are the properties of light?
What is the advantage of regular reflection over irregular reflection
What type of image is formed on a cinema screen?
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.
