    Frequency is 2.72 × 10^5 Hz

    Explanation:

    • Wavelength of light is given to be 1.10 × 10³ m. It measures the distance between two successive crests or troughs of the wave. Frequency is given by the following equation

    f = c/λ, where f is the frequency, c is the speed of light = 3 × 10^8 m/s and λ is the wavelength.

    ⇒ f = 3 × 10^8/1.10 × 10³

         = 3/1.1 × 10^8 × 10^-3

         = 2.72 × 10^5 Hz
