2. The nature of light waves
In a wave motion, there is some quantity which changes its value with time and space.
That quantity is the electric field existing in space where light travels.
The electric field is transverse to to the direction of propagation of light.
The equation of such light wave may be written as
E - E
0 sin ω(t-x/v)
Light of single wavelength is called monochromatic light.
Huygen's principle
Various points of an arbitrary surface, when reached by a wave front, become secondary sources of light emitting secondary wavelets. The disturbance beyond the surface results from the superposition of these secondary wavelets.
