Pulsed lasers used in science and medicine produce very short bursts of electromagnetic energy. If the laser light wavelength is 1062 nmnm (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.

The initials “AM” stand for amplitude modulation. Instead of fluctuating frequencies as above, they instead vary the amplitude, such that y= A(t)sin[2pif]t. Notice that the frequency is now fixed, but the amplitude will be inconsistent. Each AM station is assigned a frequency in kHz (1000 waves/second.) For example, 760AM is assigned a frequency of f=760kHz. a. What is the wavelength of the 760AM radio waves? b. Suppose a station has equation y=A(t)sin(1,850,000pit). What is this station?c.
