Imp for Phy Boards:
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
All the best ammadi!
