Question

Write any four applications of Laser.

Answer 1

1- LASERs are the beam of light (very high frequency EM wave) which is monocromatic (can be single wavelength) in nature. Which means they have very small wavelength and hence will not get absorbed by atmosphere much.
2- LASERs can carry high energy in a very concentrated space.
3- Directional. In air and vacuum, LASERs travel in straight line (If we neglect gravitational lensing).
4- They did not suffer much energy loss during traversing from one place to other, specially when moves through a guided media like optical fibre.
5- Coherence nature.
