Question

All of the following are characteristics of laser

light, except for ONE. Which one item on

the list below is NOT a characteristic of laser

light?

1. All the photons in the beamhave the same

kinetic energy to a high degree of precision.

2. All the photons in the beam have the

same momentum vector p, to a high degree of

precision.

3. Laser light is always so powerful it can

cut through thick, solid steel.

4. All the light in the beam has the same

frequency and wavelength, to a high degree of

precision.

5. Laser light is coherent.

3. Laser light is not always powerful only high power laser can cut objects like steel even cutting diamond precisely.

Low power laser are used such as pointers , scope accuracy in guns. distance measurement devices, surface smoothness checking devices etc.
