Pulsed lasers used in science and medicine produce very short bursts of electromagnetic energy. If the laser light wavelength is 1062 nm (Neodymium-YAG laser), and the pulse lasts for 35 picoseconds, how many wavelengths are found within the laser pulse? Assume that the wave travels in free space. Express your answer using two significant figures. How brief would the pulse need to be to fit only one wavelength? Express your answer to three significant figures and include the appropriate units.

To understand electromagnetic radiation and be able to perform
calculations involving wavelength, frequency, and energy.
Several properties are used to define waves. Every wave has a
wavelength, which is the distance from peak to peak or
trough to trough. Wavelength, typically given the symbol λ
(lowercase Greek "lambda"), is usually measured in meters. Every
wave also has a frequency, which is the number of
wavelengths that pass a certain point during a given period of
time. Frequency, given the symbol...

Quantized and total photon energy The particle characteristics of electromagnetic radiation are responsible for the quantized behavior of light energy. This behavior explains the results of varying the intensity and wavelength for an observed photoelectric effect, which describes the emission of electrons when light shines on a metal surface. If light only exhibited a purely wavelike behavior, then either increasing the intensity or decreasing the wavelength would both increase the rate at which electron are emitted. However, monochromatic light of...
