Walker, Halliday & Resnick — Electromagnetic Waves: Problem 44
44 A small laser emits light at power 5.00 mW and wavelength 633 nm. The laser beam is focused (narrowed) until its diameter matches the 1206 nm diameter of a sphere placed in its path. The sphere is perfectly absorbing and has density 5.00 × 10³ kg/m³. What are (a) the beam intensity at the sphere's location, (b) the radiation pressure on the sphere, (c) the magnitude of the corresponding force, and (d) the magnitude of the acceleration that force alone would give the sphere?
📝 Solution Approach
Given: 44 A, 5.00 mW
Find: (a) the beam intensity at the sphere's location; (b) the radiation pressure on the sphere; (c) the magnitude of the corresponding force
