Physics: 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.)

$E = 4.37 \times 10^{-19} J$

Explanation:

As we know that the wavelength of the photon is given as

$\lambda = 454 nm$

$h = 6.626 \times 10^{-34} Js$

$c = 2.998 \times 10^8 m/s$

now we have

$E = \frac{hc}{\lambda}$

now plug in all data in it

$E = \frac{(6.626 \times 10^{-34})(2.998 \times 10^8)}{454 \times 10^{-9}}$

now we know that

$E = 4.37 \times 10^{-19} J$
