Atomic spectra and photon energy
Explore the hydrogen spectrum, spectral series, photon energy calculations, Rydberg formula, and the relationship between wavelength, frequency, and energy.
Why this shows up in the exam
Questions often require you to calculate photon energies, identify spectral lines, and apply formulas to transitions.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Which of the following series of transitions in the spectrum of hydrogen atom falls in visible region?
Push further
More challenging21 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
A photon of green light has a wavelength of 550 nm. What is the energy of this photon in Joules? (Given: h = 6.626 x 10⁻³⁴ J s, c = 3.00 x 10⁸ m s⁻¹)
