Question 1

A helium-neon laser emits light at 632.8 nm. If the laser emits photons/second, what is its power output in mW? (c = 3.00 × 108 m/s, h = 6.626 × 10-34 J ∙ s)
◦ 28.6 mW
◦ 37.2 mW
◦ 45.7 mW
◦ 57.2 mW

Question 2

The work function of a particular metal is What is the photoelectric cutoff (threshold) wavelength for this metal? (c = 3.00 × 108 m/s, h = 6.626 × 10-34 J ∙ s)
◦ 308 nm
◦ 393 nm
◦ 473 nm
◦ 554 nm
