Answer :
The frequency of a light wave with a wavelength of 6.0 × 10⁷ and a speed of light of 3 × 10⁸ will be equal to 5.
What is Wavelength?
The distance between two identical locations (adjacent crests) in successive cycles is known as the wavelength, and it is used to describe waveform signals that are transmitted over wires or into space.
Typically, in wireless systems, this length is specified in meters (m), centimeters (cm), or millimeters (mm). The wavelength is more frequently described in nanometers (nm), which are units of 10⁻⁹ m, or angstroms, which are units of 10⁻¹⁰ m, for infrared (IR), visible light (UV), and gamma radiation.
The wavelength of the light, λ = 6.0 × 10⁷
Then the frequency of the light will be,
λ = c/f
f = c/λ
f = (3 × 10⁸)/(6.0 × 10⁷)
f = 5
