Question

The Lyman series of hydrogen spectrum lies in which region?

• A. \text{Infrared region}
• B. \text{Visible region}
• C. \text{Ultraviolet region}
• D. \text{X-ray region}

Hint:

The Lyman series corresponds to transitions of electrons to the \(n = 1\) level in hydrogen and is observed in the ultraviolet spectrum.

Answer 1

The Correct Option is C

The Lyman series in the hydrogen spectrum corresponds to transitions where electrons fall from higher energy levels to the first energy level (\(n = 1\)). The wavelengths of these transitions are in the ultraviolet region of the electromagnetic spectrum. Hence, the Lyman series lines fall within the ultraviolet range. Thus, the correct answer is Option (C).
