The citizens of a small city need to replace their coal-fired power plant. to limit their contributions to global warming, they decide to build a new power plant using the latest technologies and an abundant fossil fuel that contributes the least to global warming. their new plant will therefore use for fuel.
a. coal
b. nuclear material
c. natural gas
d. oil

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
