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.
Explanation / Answer
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.
