Question

all formulae of chapter:light of class 10th..plsss​

Answer 1

Mirror Formula :

$\boxed{\frac{1}{f} = \frac{1}{v} + \frac{1}{u} }$

Lens Formula :

$\boxed{\frac{1}{f} = \frac{1}{v} - \frac{1}{u} }$

Magnification in case of mirror :

$\boxed{ m = - \frac{v}{u} } \quad \mathtt{or} \quad \frac{h^{'}}{h}$

Magnification in case of lens:

$\boxed{ m = \frac{v}{u} } \quad \mathtt{or} \quad \frac{h^{'}}{h}$

Snell's Law :

$\boxed{ \frac{\sin i}{ \sin r } = \mathtt{n} }$

Power of a lens:

$\boxed{ P = \frac{1}{f} }$
