Newton's 2nd Law states An object acted on by an unbalanced force will accelerate in the direction of that
force, in direct proportion to the strength of the force, and in inverse proportion
to the mass of the object.
For every action there is an equal and opposite reaction
Objects in motion will stay in motion; objects at rest will stay at rest unless an
unbalanced force is applied.

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
