Light reflection and refraction:

*R=2f

*Mirror formula:

1/v+1/u=1/f

m=hi/hi(or)-v/u

Concave-

hi=-ve

ho=+ve

f=-ve

u=-ve

v=-ve

Convex-

u=-ve

v=+ve

f=+ve

hi=+ve

ho=+ve

*Lens formula:

1/v-1/u=1/f

m=hi/ho(or)v/u

*P=1/f

*P=P1+p2+p3+…........+on

Electricity:

*I=Q/t

*V=W/Q

*V=IR

*R=pL/A

*RS=R1+R2+R3+........

*1/Rp=1/R1+1/R2+.......

*P=vi

*H=i2rt
