Question 16 of 25

What is the energy of a photon emitted with a wavelength of 654 nm?
A. 1.01 * 10-27 J
B. 4.33 x 10-22
C. 1.30 x 10-22 j
D. 3.04 10-19 J

Answer 1

D. 3.04 × 10^-19 J

Step-by-step explanation:

c = lambda * nunu = c/lambda

E = h* nu

E = h * c/lambda = 6.626x10^-34 J-sec * 3x10^8 m/sec / 6.54x10^-7 m

E = 3.04x10^-19 J
