Solved: Lasers are classified according to the eye-damage danger they pose. Class 2
Chapter 29, Problem 48(choose chapter or problem)
Lasers are classified according to the eye-damage danger they pose. Class 2 lasers, including many laser pointers, produce visible light with no greater than 1 mW total power. Theyre relatively safe because the eyes blink reflex limits exposure time to 250 ms. Find (a) the intensity of a 1-mW class 2 laser with beam diameter 1.0 mm, (b) the total energy delivered before the blink reflex shuts the eye, and (c) the peak electric field in the laser beam.
