Question

Hand written all formula of physics light reflection and refraction class 10.

Answer 1

Explanation:

1/f = 1/u + 1/v (f=focal lenght of mirror)

f = r/2

M = hi/ho

M= -v/u

Formula related to refraction of light:

n=sini/sinr (n=refractive index)

1/f=1/v -1/u

p=1/f(m) or 100/f(cm) (p= power of lens)

m= I/O

Magnification h'/h

Power of lens; P=1/f
