Calculate the frequency of light having a wavelength of 425nm. remember that 1nm=1×10−9m
Gnom [1K]

The frequency of light having a wavelength of 425nm will be 70588 × 10^{14} Hz.

The count of times an event takes place per unit of time is known as its frequency. The word frequency would be most frequently used to describe waves in physics including chemistry, including light, sound, including radio waves. The frequency refers to the number of times during one second that a point on a wave crosses a fixed reference point.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places  in the consecutive cycles.

Given data:

wavelength = 425nm = 425 * 10^{-9} m

Frequency can be calculated by using the formula;

Frequency =  speed of light / wavelength

Frequency = 3 × 10^{8} m/s / 425 × 10^{-9} m = 7,0588 × 10^{14} Hz.

Therefore, the frequency of light having a wavelength of 425nm will be 70588 × 10^{14} Hz.
