Pulsed lasers are very similar to regular lasers, except they don't continuously emit laser light. Baby spice is looking at one on Ebay, and she finds a pulsed He-Ne laser that emits a cylindrical
beam of light with a diameter of 0.750 cm. Each pulse lasts for 1.30 ns, and each burst contains an amount of energy equal to 3.00 J. Baby Spice has the following questions about this laser.
(a) What is the length of each pulse of laser light?
m
(b) What is the average energy per unit volume for each pulse?
J/m³
O The electron transitions to the n 2 state.
O The electron transitions to the n = 5 state.
O The electron is captured by the nucleus.
A hypothetical atom has three energy levels: the ground-state level and levels 1.25 eV and 2.75
eV above the ground state. When this atom is in the ground state, what wavelengths of light
may it absorb? Let Planck's constant h = 4.136 x 10 eV s, and the speed of light c= 3.00 x
10° m/s.
O451 nm and 993 nm
O 451 nm, 827 nm, and 993 nm
O 827 nm and 993 nm
O451 nm and 827 nm
Chemists use infrared absorption spectra to identify chemicals in a sample. In one sample, a chemist finds that light of wavelength 5.8 um is absorbed when a molecule makes a transition from its ground harmonic oscillator level to its first excited level.
