Balmer series of hydrogen atom lies in

Options

A. microwave region
B. visible region
C. ultraviolet region
D. infrared region

Explanation

To determine the region in which the Balmer series of the hydrogen atom lies, we can follow these steps:

### Step 1: Understand the Balmer Series
The Balmer series refers to the set of spectral lines that are emitted when an electron in a hydrogen atom transitions from a higher energy level (n ≥ 3) to the second energy level (n = 2).

### Step 2: Identify the Regions of the Electromagnetic Spectrum
The electromagnetic spectrum is divided into several regions based on wavelength:
- Radio waves
- Microwaves
- Infrared
- Visible light
- Ultraviolet
- X-rays
- Gamma rays

### Step 3: Locate the Balmer Series in the Spectrum
The Balmer series specifically corresponds to wavelengths that fall within the visible light range of the electromagnetic spectrum. The visible spectrum typically ranges from about 400 nm (violet) to 700 nm (red).

### Step 4: Conclusion
Since the Balmer series transitions result in the emission of light that falls within the visible range, we conclude that the Balmer series of the hydrogen atom lies in the visible region of the electromagnetic spectrum.

### Final Answer
The Balmer series of the hydrogen atom lies in the visible region.
