Question

What is the energy of a photon of violet light with a frequency of 7.57x10^14 s^-1?

Answer 1

ΔE = 5.02 x 10⁻¹⁹ j

Step-by-step explanation:

ΔE (photon) = h·f = (6.63 x 10⁻³⁴ j·s)(7.57 x 10¹⁴ s⁻¹) = 5.02 x 10⁻¹⁹ j

h = Planck's Constant = 6.63 x 10⁻³⁴ j·s

f = frequency (given) = 7.57 x 10¹⁴ s⁻¹
