DIFFERENCE BETWEEN REGULAR AND IRREGULAR REFLECTION?
answer me fast.................
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..
What is lateral inversion
Two transparent mediaAandBare separated by a plane boundary. The speed of light in mediumAis2.0 × 108m/s and in mediumBis 2.5 × 108m/s. The critical angle for which a ray of light going fromAtoBsuffers total internal reflection is

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.
