A laser emits light at power 1.50 mWand wavelength 633 nm. The laser beam is focused (narrowed) untilits diameter matches the 1266 nm diameter of a sphere placed in its path. The sphere is perfectly absorbing and has density5.50 103 kg/m3.
(a) What is the beam intensity at the sphere'slocation?
(b) What is the radiation pressure on the sphere?
(c) What is the magnitude of the corresponding force?
(d) What is the magnitude of the acceleration that force alonewould give the sphere?
