Question

all formula's of light reflection and refraction class 10​

Answer 1

Formula related to reflection of light:

* 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

this are the formulas

hope it will be usefull
