If the hydrogen atom emits red, blue-green, blue, and violet light, how many energy levels does it have in the visible region of the spectrum? A. 3
B. 4
C. 5
D. 6

If a hydrogen atom emits red, blue-green, blue, and violet light, the number of energy levels it has in the visible region of the spectrum is: B. 4

An electromagnetic spectrum can be defined as a range of frequency and wavelength that an electromagnetic wave is distributed (extends).

Generally, the electromagnetic spectrum comprises the following:

When the atom of an element emits a radiation, each color of the radiation represents an energy level within the visible region of the electromagnetic spectrum.

Since the hydrogen atom emitted four colors (red, blue-green, blue, and violet light), it has four (4) energy levels in the visible region of the electromagnetic spectrum.

The correct answer is - option B. 4.

Explanation:

The visible spectrum of light emitted by a sample of active or excited hydrogen atoms splits into four wavelengths that are basically four distinct levels of energy in the visible region of the spectrum. There four different wavelengths are 410 nm, 434 nm, 486 nm, and 656 nm.

These shows for colors according to the spectrum and wavelength violet, blue, green, and red, where 656 nm wavelength is most intense on the spectrum.
