Explanation First calculate the total energy of photons on playing CD player. Given The power level of the CD player is 0 .10 mW . The wavelength of photon is 780 nm The time duration of playing the CD player is 69 min . The conversion of milliwatt ( mW ) into watt ( W ) is done as, 1 mW = 10 − 3 W Hence, the conversion of 0 .10 mW into watt ( W ) is, 0 .10 mW = 10 − 3 W 1 mW × 0 .10 mW = 0 .10×10 − 3 W Hence, the power level of the CD player is 0 .10×10 − 3 W . The conversion of minutes ( min ) into seconds ( s ) is done as, 1 min = 60 s The conversion of 69 min into seconds ( s ) is, 69 min = 60 s 1 min × 69 min = 4140 s Hence, the time duration of playing the CD player is 4140 s . The total energy of photons on playing CD player is calculated by the formula, Total energy = Power × Time Substitute the value of power and time in the above equation, Total energy = 0 .10×10 − 3 W × 4140 s = 0.414 J Hence, the total energy of photons on playing CD player is 0.414 J . Now, calculate the energy of one photon having wavelength 780 nm
