Physics Question

Pulsed lasers used in science and medicine produce very short bursts of electromagnetic energy. If the laser light wavelength is 1062 nm (this corresponds to a Neodymium-YAG laser), and the pulse lasts for 40 picoseconds, and 1.1 x 104 wavelenghs are found in the laser pulse, how short would the pulse need to be to fit in one wavelength?

  1. frequency*wavelength=speedlight
    1/period*wavelength=speedlight

    period= wevelength/speedlight solve it.
