Answer:
If you mean 6.00 x 10^14 s^-1 then your answer is 3.98^-19 Joules
Step-by-step explanation:
use this equation Ephoton=hν
where h=6.626×10^−34J⋅s Planck's constant and ν = frequency
so Ephoton=(6.626×10^−34J⋅s )(6.00 x 10^14 s^-1 )
the reciprocal seconds and seconds cancel each other out , multiply teh remaining and use joules as your unit
