Q. Why does the sky appear blue in colour? As-per to the Rayleigh's scattering law the shorter wavelengths are scattered much more than the longer wavelengths. The blue look o
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
Explain Newtons Third Law - Linear Motion Stating that a force is just a push or a pull is a bit of a simplification. If we exert a push or a pull on an object then the object
A gas is compressed from 400 cm3 to 200 cm3 at a constant pressure of 100 kPa. At the same time, 100 J of heat energy is transferred out of the gas. What is the change in internal
