What does “Polarisation” actually mean in Wave Optics, and why does it matter for JEE?
light is a transverse wave, so its vibrations can be restricted to one plane — something only transverse waves can do.
In simple words: light is a transverse wave, so its vibrations can be restricted to one plane — something only transverse waves can do. Getting Polarisation clear matters because JEE questions on Wave Optics usually test this idea directly, not just a formula you memorised.
Key point
Polarisation
Common mistake
thinking sound can be polarised too.
Memory tip
only transverse waves (light) polarise; longitudinal (sound) can't.
