Question

laser beam is characterized by
A) low spectral width
B) high power but low intensity
C) rays of light which focus on a point without a convex lens
D) low wavelength​

Answer 1

As a tool, the laser beam is characterised by certain properties. Fundamental properties of laser light are its monochromatic nature (one wavelength) and directionality (narrow divergence). In contrast to the beam from a normal light source, laser beams can be very sharply focused.
