Frequently asked questions
What makes a Electromagnetic Waves question "important" for JEE?
Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.
Which subtopics in Electromagnetic Waves are high-weightage?
Key areas include Displacement current, electromagnetic waves and their characteristics, transverse nature of electromagnetic waves, Electromagnetic spectrum (radio waves, microwaves, infrared, visible, ultraviolet, X-rays, Gamma rays), applications of electromagnetic waves. Prioritise these before moving to edge cases.
How many important questions should I revise?
Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.
Can I practise only important questions on Goodmarks?
