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 gl..

Thus, this chapter on refraction helps us understand many natural phenomena like the twinkling of stars, the sparkling of diamonds, mirage etc. It also throws light on the working of the human eye and the defects of visio..

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. W..

Tracing the Path of Light Through a Prism - Place a prism on a white sheet of paper with the triangular face on the sheet and trace its boundary ABC. Fix two pins T and S on one side. Place the prism on the boundary ABC. Looking through the other side fix two more pins Q and R in such a way that th..

Scattering is a general physical process whereby some forms of radiation, such as light or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which it passes. A large number of molecules are present in..

Myopia - You must have seen some people holding books very close to their eyes. This is because they suffering from myopia (short sightedness). A myopic person cannot see distant objects clearly because the far point of his eye is less than infinity. Myopia is the defect of the ..
