b. Calculate the wavelength of the photon in nanometers. Show all of your work and units to receive full credit.
Answer:
a) 5 × 10^14 Hz
b) 5.98 × 10^-7 m
Step-by-step explanation:
a)
Recall the formula;
E = hf
Where;
E= energy of the photon = 3.313 x 10-19 J
h= planks constant = 6.6 × 10^-34 Js
f= frequency of the photon (the unknown)
f= E/h = 3.313 x 10-19 J/6.6 × 10^-34 Js
f= 5 × 10^14 Hz
b)
From;
E= hc/λ
h= planks constant = 6.6 × 10^-34 Js
c= speed of light = 3 × 10^8 m/s
λ = wavelength of photon (the unknown)
λ= hc/E
λ = 6.6 × 10^-34 Js × 3 × 10^8 m/s/3.313 x 10-19 J
λ = 5.98 × 10^-7 m
