Ozone absorbs energy with a frequency of 1.29 × 10^15 s^-1.a)the wavelength (in nm) of the absorption?c) the energy absorbed by one photon?

(a)
Speed of light, c = 3.00 × 10⁸ m⁻¹
Frequency of light, ν = 1.29 × 10¹⁵ s⁻¹

c = ν λ
Wavelength, λ = c/ν = (3.00 × 10⁸ m⁻¹) / (1.29 × 10¹⁵ s⁻¹) = 2.33 × 10⁻⁷ m = 233 nm


(c)
Planck constant, h = 6.626 × 10⁻³⁴ J s

Energy absorbed by one photon, E = h ν = (6.626 × 10⁻³⁴ J s) × (1.29 × 10¹⁵ s⁻¹) = 8.55 × 10⁻¹⁹ J
