How does a LASER work? Include the terms “simulated emission”
and “population inversion” in your answer. Be able to draw a
diagram and label the components. Which components of a
monochromater influence bandwidth?
what factors influence the resolution and dispersion of a
grating What is the difference between resolution and
dispersion?
A beam of wavelength 310 nm from a laser is incident on a metal
with work function 2.7 eV. The power of the laser is 0.15 W.
(a) Does the metal emit photoelectrons? Why?
(b) What is the range of photoelectron kinetic energies emitted
by metal?
(c) What is the range of de Broglie wavelengths of these
photoelectons?
(d) How does result for part (b) change if the laser power is
doubled to 0.30 W?
Thank you.
