Question

Microwaves travel at the speed of light, 3x108m/s. When frequency of the microwaves is 9×109 Hz, quantitatively translate this information into their wavelength and period. Wavelength= 0.03m; period 1.1×10-10s , , Wavelength= 0.03m; period 1.1×10 -10 s, Wavelength= 0.03m; period 1.1×10-10s Wavelength= 0.03m; period 1.1×10 -10 s, Wavelength = 0.03cm; period 1.1x109s Wavelength = 0.03cm; period 1.1×10 9 s, Wavelength=0.03m; period 1.1x1010s

    Explanation:

    Given that,

    The frequency of microwaves, f=9\times 10^9\ Hz

    The time period of the wave is :

    t=\dfrac{1}{f}\\\\t=\dfrac{1}{9\times 10^9}\\\\t=1.1\times 10^{-10}\ s

    Let \lambda is the wavelength of the wave. We know that,

    v=f\lambda\\\\\lambda=\dfrac{v}{f}

    Put all the values,

    \lambda=\dfrac{3\times 10^8}{9\times 10^{9}}\\\\\lambda=0.03\ m

    Hence, this is the required solution.
