Interpretation Introduction To determine: The wavelength. Explanation Given: Power of laser P = 20 .0 mW . Time t = 1 .00 hr . Number of photons emitted per hour N =2 .29 × 10 20 photons . Explanation: Power is the energy emitted per unit time. Convert the units of power as follows: 20 .0 mW × ( 1 W 1000 mW ) × ( 1 Js − 1 1 W ) = 0 .02 Js − 1 Calculate the energy emitted in one hour as follows: ( 2 .0 × 10 -2 Js − 1 ) × 1 .00 hr × ( 3600 s 1 .00 hr ) = 72.0 J Calculate the energy of one photon when 2 .29 × 10 20 photons are emitted per hours as follows: 72.0 J × ( 1 2 .29 × 10 20 photons ) = 31
