7.5 × 10¹⁴ Hz is the highest frequency of visible light when wavelengths of visible light range from 400 nm to 700 nm.
The number of oscillations of a wave per unit of time, measured in hertz, is the definition of frequency (Hz).
The pitch and frequency are inversely correlated. Noises of frequency between 20 and 20000 Hz can be heard by humans.
The distance between the two closest locations that are in phase with one another is known as a wavelength. As a result, a single full wavelength separates two nearby peaks or troughs on a wave.
Typically, the wavelength of a wave is denoted by the letter lambda (λ).
The distance a wave travels in one unit of time is known as the wave speed (v). Taking into account that the wave travels one wavelength in one interval,
v=λ/T
Given that T = 1/f, we can write the equation above as,
V = f λ
The link between frequency and wavelength is implied by the fact that the wave speed is equal to the product of its frequency and wavelength.
As the frequency and wavelength are inversely proportional to each other so the frequency is highest for the minimum wavelength.
Given
Minimum wavelength of visible light = 400 nm = 4 × 10⁻⁷ m
Speed of light = 3 × 10⁸ m/s
Frequency = c/λ = 3 × 10⁸ / 4 × 10⁻⁷
= 7.5 × 10¹⁴ Hz
