Write a short note on the human eye . ( all important points ) .... ( give answer accndg to the chapter " Light " )
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.
plzz... reply fast. URGENT ... plz ... plz..

can anyone give me the ray diagrams of concave and convex mirrors
how could i make model for human eye
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.
