Question

angular speed of laser beam is given by a relation​

Answer 1

Answer:

Theoretically the angle of spread of the laser beam, in radians, would be its narrowest diameter divided by the wavelength of light. If the beam were 1 mm in diameter then its angular spread would be: A = L/d = 6 x 10-7 m/10-3 m = 6 x 10-4 radians or 60 milliradians. d = A x D = 6 x 10 -4 x 10 = 6 x 10 -3 m = 6 mm.
