The frequency obtained for the violet visible light is 7.1 × 10^14 Hz.

What is frequency?

The frequency of a wave refers to the number of cycles completed per unit time. The unit of frequency is Hz or cycles per second.

For the ultraviolet light, wavelength =  420 nm

Frequency = speed/wavelength

Frequency =  3 × 10^8 m/s/ 420 × 10^-9 m

Frequency = 7.1 × 10^14 Hz
