Question

what is laser light what is difference between light and laser light

Answer 1

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation
The major difference between the laser and light is in terms of the coherence. The laser is the unidirectional, monochromatic and coherent beam of light whereas in normal incandescent bulbs photons emit according to their wavelengths, polarization and path of travelling.

Answer 2

The main difference between ordinary light(i.e the light comes from incandescent lamp) and laser light is :

1. Coherence : Ordinary light diverges in all directions whereas the light from laser does not diverge.

2. Monochromaticity: Laser beams are monochromatic (i.e. of single wavelength only) whereas ordinary light is non-monochromataic ( i.e. mixed wavelength is mixture of different colors).
