1. Flashlight (10) A 6.0V flashlight draws 0.20 A of current. Only about 1 % of the power dissipated is converted into light (A = 550 nm). Assume the beam has a diameter of 8.0 cm, and is approximately cylindrical. Find the number of photons emitted per second and the number of photons per meter of the beam. What is the flux density of the beam as it leaves the flashlight ?
