What is the wavelength of violet light?

Violet light has a wavelength range that typically falls between approximately 380 nm to 450 nm. The choice indicating 390 nm accurately reflects a wavelength that falls within this range, making it characteristic of violet light.

The understanding of light wavelengths is fundamental in understanding the electromagnetic spectrum and the visible light range, which encompasses violet as the shortest wavelength visible to the human eye. When discussing wavelengths, it's essential to remember that shorter wavelengths correspond to higher energy and different colors of light. Therefore, the choice of 390 nm identifies violet light accurately, establishing it as the correct answer.
