Light beam which is highly directional is called: (1) eraser (2) grazer (3) maser (4) laser
by

1 Answer

Answer :

(4) laser Explanation: Laser light is very different from normal light. It is very directional, has a very tight beam and is very strong and concentrated. The light released is monochromatic. It contains one specific wavelength of light (one specific colour).

Laser is a device to produce - (1) a beam of white light (2) coherent light (3) microwaves (4) X-rays

Description : Laser is a device to produce - (1) a beam of white light (2) coherent light (3) microwaves (4) X-rays

Last Answer : (2) coherent light Explanation: In physics, two wave sources are perfectly coherent if they have a constant phase difference and the same frequency, and the same waveform. Coherence is an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference.
