Determine how much energy enters your eye per second

Reference no: EM13516330

You are standing 1.9m from a 130W- lightbulb.

a. If the pupil of your eye is a circle 5.0mm in diameter, how much energy enters your eye per second? (Assume that 5.0% of the lightbulb's power is converted to light.).

b. Repeat part A for the case of a 1.0mm--diameter laser beam with a power of 0.50.
