Even though all colours of the visible spectrum travel with the same speed in vacuum, the speed of the colours of the visible spectrum varies when they pass through a transparent medium like glass and water. That is, the refractive index of glass is different for different colours. When a poly..

Ecosystem - Definition - An ecosystem can be defined as 'a structural and functional unit of biosphere or segment of nature consisting of community of living beings and the physical environment, both interacting and exchanging materials between them'. E. P. Odum, an American ecologist, defined ecol..

According to wave mechanics, we cannot simply say that the electron exists at a particular point but we talk about certain regions in space around the nucleus where the probability of finding the electron is maximum. Such regions are expressed by mathematical expressions and are called orbital wave..

Initially water floats on top of the CuSO 4 solution as it is less dense. The boundary line very soon disappears and after a few hours the solution becomes a homogeneous pale blue color as shown in figure. The intermingling can be explained by describing the motion of molecules of water, ..

Dispersion of White Light By a Glass Prism - Even though all colours of the visible spectrum travel with the same speed in vacuum, the speed of the colours of the visible spectrum varies when they pass through a transparent medium like glass and water. That is, the refractive index of glass is diff..

Place a rectangular glass slab on a white sheet of paper fixed on a drawing board. Trace the boundary ABCD of the glass slab. Remove the glass slab and draw a normal N 1 N 2 at O. Draw a straight line IO inclined at an angle say 30 o with the normal. IO is the incident ray. ..

The size of the atom is significant in governing its property. If the atom is assumed to be spherical, then the radius of the sphere gives the atomic radius. But it is difficult to exactly determine the radius of the atom because The probability of finding the electron is never zero even at larg..

Dispersion of White Light By a Glass Prism - Even though all colors of the visible spectrum travel with the same speed in vacuum, the speed of the colors of the visible spectrum varies when they pass through a transparent medium like glass and water.

Refraction of Light through a Glass Slab - Let us now perform an experiment and find out how light gets refracted when it is incident on a rectangular glass slab. Place a rectangular glass slab on a white sheet of paper fixed on a drawing board. Trace the boundary ABCD of the glass slab. ..
