Properties of Electromagnetic spectrum:
A spectrum can be divided into 3 regions. They are UV region, Visible region and IR region. Monochromatic light is a light which consists of one colour wavelength .A light which is a mixture of several colours (wavebands) is called polychromatic light.
The waves travelling with velocity of light and consisting of oscillating electric and magnetic fields perpendicular to each other and also perpendicular to the direction of their propagation are called 'electromagnetic waves'.
Net force acting on particle of mass 2 kg is 10N in north direction.At t=o, particle was moving eastwards with 10m/s. Find displacement and velocity of particle after 2 seconds.
Hubble's law (E.P. Hubble; 1925): A relationship discovered among distance & radial velocity. Further away a galaxy is away from is, the quicker it is receding away from us. T
