The Helium-Neon laser used in many labs and demos emits red light with wavelength of 0.6328 ?m. If the total power in the laser beam is 0.35 mW, calculate how many photons of red light emerge from the laser every s. Data: Planck's constant (h) = 6.626075 × 10-34 J ·s; Speed of light = 3.00 × 108 m/s.
