Question

14.48) Name three characteristic properties of a laser.

Expert Solution

Step 1

Characteristic properties of a laser:

Coherence: Laser light are highly coherent because emission of photons in laser have same energy, frequency, or wavelength, which gives single wavelength.

Highly directional: Photons in laser travels in same direction; therefore, laser emits light in only one direction.

Monochromatic: The energy, frequency, or wavelength of emitted photons are same, which gives single wavelength or colour. Hence, laser light are monochromatic.
