Question

A certain type of laser emits light that has a frequency of 4.6 x 1014 Hz. The light, however, occurs as a series of short pulses, each lasting for a time of 3.1 x 10-11s. The light enters a pool of water. The frequency of the light remains the same, but the speed of light slows down to 2.3 x 108 m/s. In the water, how many wavelengths are in one pulse

    Answer:

    14,260

    Explanation:

    Relevant data provided for computing the wavelengths are in one pulse is here below:-

    The number of wavelengths in Ls = 4.6\times 10_1_4

    Therefore the Number of in time = Δt = 3.1\times 10_-_1_1

    The number of wavelengths are in one pulse is shown below:-

    Number\ of\ wavelengths = \triangle t\times f

    = 3.1\times 10_-_1_1\times 4.6\times 10_1_4

    = 14,260

    Therefore for computing the number of wavelengths are in one pulse we simply applied the above formula.
