The visible region of hydrogen spectrum was first studied by

visible line of hydrogen spectrum will be

Assertion: Lyman series lies in the visible region of electromagnetic spectrum. Reason: This is because Balmer series also lies in visible region.

The Balmer series of lines in the hydrogen spectrum appear in the visible region of the electromagnetic spectrum. Calculate the wave number of the second line in the Balmer series.

The longest wavelength in the ultraviolet region of the hydrogen spectrum is 120nm. What is the smallest wavelength in the infrared region of the hydrogen spectrum ?

The largest wavelength in the ultraviolet region of the hydrgoen spectrum is 122nm. The smallest wavelength in the infrared region of the hydrogen spectrum ( to the nearest integer )is :

Which one of the series of hydrogen spectrum is in the visible region ?
