The energy of one photon of light is related to wavelength (λ) of light using the equations: for green light with a wavelength of 454 nm, the energy (in joules) can be calculated using the following values: plank's constant (h) = 6.626 x 10-34 j*s speed of light (c) = 2.998 x 108 m/s wavelength (λ) = 454 x 10-9 m. calculate the energy (in j) of a green photon and enter your answer using three significant figures and exponential notation. (for example, 456000 would be entered as 4.56e5.)
