What are the answers to the last two columns and how do I solve them?

f = 5.08 x 10¹⁴/s

E=3.366 x 10⁻¹⁹ J

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

I will give example number 1, and for subsequent numbers, the steps will be the same

For NaNO₃ with λ=590 nm=5.9 x 10⁻⁷m

Frequency(f) :

Energy(E) :

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being
