Consider a red light with  = 750 nm and a green light  = 550 nm (a) Which light travels a greater distance in 1 second, red light or green light? Explain. (b) Which light (red or green) has the greater frequency (that is, contains more waves completed in 1 second)? Explain. (c) What are the frequencies of the red and green light, respectively? (d) If light energy is defined by the quantum formula, such that Ep = h, which light carries more energy per photon? Explain. (e) Assuming that the speed of light, c = 2.9979 x 108 m/s, Planck’s constant, h = 6.626 x 10-34 J.s., and Avogadro’s number, NA = 6.022 x 1023/mol, calculate the energy: (i) per photon; (ii) per mole of photon for green and red light, respectively

Question

Consider a red light with  = 750 nm and a green light  = 550 nm
(a) Which light travels a greater distance in 1 second, red light or green light? Explain.
(b) Which light (red or green) has the greater frequency (that is, contains more waves completed in 1
second)? Explain.
(c) What are the frequencies of the red and green light, respectively?
(d) If light energy is defined by the quantum formula, such that Ep = h, which light carries more
energy per photon? Explain.
(e) Assuming that the speed of light, c = 2.9979 x 108 m/s, Planck’s constant, h = 6.626 x 10-34 J.s., and
Avogadro’s number, NA = 6.022 x 1023/mol, calculate the energy: (i) per photon; (ii) per mole of
photon for green and red light, respectively
