Answer 1

The correct option is 380-450.

Key Points

Violet light has a wavelength of around 400 nm. Because it is visible light comes in the range of 380nm to 700 nm.

Additional Information

Electromagnetic spectrum:

The collection of different types of radiation from gamma rays to radio waves with their frequency and wavelength range is in a particular order.

Wavelength:

It is the separation between the corresponding points of two successive waves. Two points or particles in the same phase are referred to as "corresponding points."

Radiation:

In physics, it is the flow of atomic and subatomic particles, along with waves.
Examples: Heat rays, light rays, and X-rays.

Waves:

The regular, systematic spread of disturbances from one location to another.
The waves that travel on the water's surface are the most well-known, but waves also exist in sound, light, and the movement of subatomic particles.
The disturbance oscillates regularly (see the periodic motion) with a set frequency and wavelength in the simplest waves.
