Question

all formula's of light reflection and refraction​

Answer 1

Answer:

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

Explanation:

Answer 2

Answer:

$1 \div v + 1 \div u = 1 \div f \\ thi s \: is \: mirror \: formula$

$magnification \: = m \: = - v \div u \\ or \: m \: = height \: of \: image \: \div height \: of \: object \: \\ this \: is \: used \: for \: mirrors \: only$
