Spectral series ke numericals dhyaan mein rakhna

TIR ke conditions and applications

Relation between i(c) and refractive index

Combo of lenses: magnifications are multiplied, powers are added

In combo of lenses, if final power is neg, then concave/diverging effect, if pos, then convex/converging effect

Combo lenses ke qs padke jaana

Compound microscope, telescope aur cassegrain telescope ke ray diagrams aur features padhke jaana

Radar mein micro waves, detection in body mein x rays, killing cancerous cells mein gamma rays, infrared waves are responsible for green house effect

If they give direction of Electric field and ask propagation of em wave, then use right hand rule (trick hai, likha nahi hai)

Interference is always YDSE while diffraction is single slit

Einstein quantised photoenergy while Bohr quantised angular momentum

Spectral series mein n1 is always the initial stage and is greater than n2 that is end stage

Spectral series ke equation se wavelength comes in metre

Nuclear force ke 3 features padhke jaana

Nuclear fission vs fusion (at least 1 equation each)

Section C mostly will be Ray optics only

Try showing some diagram in as many questions as possible: graphs, sc diagrams, energy band diagrams, circuits etc. and draw in pencil

Clearly likho meri maa aur lines 4 chodna har question ke baad jic
