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?
W/m2
(b) What is the radiation pressure on the sphere?
Pa
(c) What is the magnitude of the corresponding force?
N
(d) What is the magnitude of the acceleration that force alonewould give the sphere?
m/s2
