Aphoton has a frequency of 7.3 × 10–17 hz. planck’s constant is 6.63 × 10–34 j•s.

the energy of the photon, to the nearest tenths place, is × 10–50 j.

current flows in a wire

the inner core.

good luck: )

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
