Answer from: Quest
you'd use the equation that establishes a relationship between energy and wavelength, which looks like this
e=h⋅cλ, where
λ - the wavelength of the photon; c - the speed of light, usually given as 3⋅108m/s; h - planck's constant, equal to 6.626⋅10−34j s
plug the value you were given for the energy of the photon in the above equation to get the wavelength
e=h⋅cλ⇒λ=h⋅ce
λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
Answer from: Quest
