Question Details:
An argon laser emits 1 watt of continuous light (λ= 5.145 x 10-7 m) in a parallel beam of 2 mm diameter in vacuum.
(a) What is the wavelength, frequency, period, wave number, velocity, intensity, and amplitude of the electric field of the laser light?
b) What is the energy, the linear and angular momenta carried by each photon? What is the photon flux (the number of photons per time) of the laser light?
(c) Assume that the laser beam is incident normally (θi = 0°) on the flat surface ofa body. What pressure is exerted on the body when it fully absorbs the laser light? Ifthe body fully reflects the laser light back, what is the pressure exerted on the body?
(d) The laser beam is incident normally (θi = 0°) on the flat surface of a transparent glass block of refractive index n=1.5, and only the 96% of the incident power enters into the block. Which of the above quantities in (a) and (b) change for the transmitted light inside the glass block and what are
the new values for the changed quantities.
I know it's a lot. I'll take any help/hints I can get. Thanks in advance. :)
