Question

Quizplus · Accepted Answer

We can use the equation E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Plugging in the values we get:
E = (6.626 × 10^-34 J s)(2.998 × 10^8 m/s)/(550 × 10^-9 m)
E = 3.61 × 10^-19 J
Therefore, the energy of a wavelength of light of 550 nm is 3.61 × 10^-19 J, which corresponds to choice C.
