WAVELENGTH OF LASER || DETERMINATION OF WAVELENGTH OF LASER || ENGINEERING PHYSICS LAB || LASER

A laser is produces a very narrow beam of light that is useful in many technologies and instruments. The letters in the word laser stand for Light Amplification by Stimulated Emission of Radiation.
The letters in the word laser stand for Light Amplification by Stimulated Emission of Radiation. A laser is an unusual light source. It is quite different from a light bulb or a flash light. Lasers produce a very narrow beam of light. This type of light is useful for lots of technologies and instruments-even some that you might use at home!
Light travels in waves, and the distance between the peaks of a wave is called the wavelength.

Sir wavelength of laser final value tell me

[@senthilssmphy3038]

6000 to 7000 A' approximately
Wavelength defer by the sources
