Question

The absorption spectrum of neon has a line at 633 nm. What is the energy of this line? (The speed of light in a vacuum is 3.00 x 108 m/s, and Planck's constant is 6.626 x 10-34 J·s.)

Answer 1

B

Step-by-step explanation:

E = hc/
`\lambda`. Remember, it is in meters not nanometers so you have to convert. You end up with B.
