Atomic Structure
What's happening? Hydrogen spectrum lines come from electron transitions between energy levels. Lyman (UV): n=1. Balmer (visible): n=2. Paschen (IR): n=3. Rydberg formula: 1/λ = R(1/n1^2 - 1/n2^2).
Why this matters for JEE

Hydrogen Spectrum is a most-searched and high-weightage topic in JEE Chemistry.

This concept appears in 1-2 questions every year. Understanding it visually builds the intuition needed to solve numerical problems fast.

Key formula

Core Formula

1/λ = R(1/n1² - 1/n2²)

Adjust the controls above and watch how changing each variable affects the result in real time.

JEE Application

This is one of the most-tested concepts in JEE. Master the formula and the visual intuition together.

Step-by-step

How to approach Hydrogen Spectrum problems

  1. Identify the variables — list what's given and what's asked.
  2. Apply the core formula — 1/λ = R(1/n1² - 1/n2²).
  3. Check units — convert to SI units before calculating.
  4. Verify with intuition — does the answer make chemical sense?
