Structure and working of Human Eye- Video

The human eye is an organ which reacts to light and pressure. As a sense organ, the mammalian eye allows vision. Human eyes help provide a three dimensional, moving image, normally coloured in daylight. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can differentiate between about 10 million colors and is possibly capable of detecting a single photon.

Lateral Shift – Note Class 11

Lateral Shift

When a ray of light incident on a glass slab then emergent ray coming out of the slab will be parallel to initial direction of incident ray.

The Perpendicular distance between emergent ray and initial direction of incident ray is called Lateral Shift.

It is denoted by delta “δ” .

iota Ι ι 0921 0953
kappa Κ κ, ϰ 0922 0954, 1008
lambda Λ λ 0923 0955
mu Μ μ, µ 0924 0956, 0181
nu Ν ν 0925 0957

* There are two variants of lowercase sigma. The second is used only at the end of Greek words and (to the best of my knowledge) never as a symbol by itself.

Some Must Have Science Android Apps

Now a days ,As we all have the Smartphone . We used to run different apps that are of different category . If we are the student of science we really want some interesting apps, that will help us to go ahead on the field of science. So i have collected some must have cool and best science apps that runs on Android based smart Phone.

So let’s have a look.
