A puck of mass 0.30 kg is sliding along an essentially frictionless patch of ice at 6.0 m/s. It encounters a rough patch of ice with a coefficient of kinetic
friction of 0.10. How long will it take the puck to stop and how far will it travel?

radiation

explanation:

heat is transmitted by radiation

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
