Q. High Powered Industrial Laser's output is pulsed, and produces 460 nm monochromatic light. Power of each pulse described by the function: P = 100 - (t-C)^2 + 0.25 (t-C)^4. P is measured in watts and C = square root of 20 seconds. Laser turns on when t = 0 seconds and shuts off when t = 2C seconds. a) Graph the power of the laser when it's on. b) Compute the energy in the pulse. c) Compute the number of photons in the pulse.
