Ray and wave optics appear every year — lens/mirror formula, refraction and Young's double-slit are standard.
1/v + 1/u = 1/f; apply the sign convention strictly
n = sin i / sin r; lens-maker's formula for combinations
Occurs beyond critical angle sinθc = 1/n
Fringe width β = λD/d; bright fringes at path diff = nλ
Know the lens formula sign convention and YDSE fringe width β = λD/d.
On average, 3 questions per paper come from Optics — about 100% of the Physics paper, worth roughly 15 marks.
It is rated Medium. Know the lens formula sign convention and YDSE fringe width β = λD/d.
