Question

give me all formulas of light- reflection and refraction

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

Answer 2

Answer:

The important formulae from the chapter light-reflection and refraction are:

The mirror equation.

Magnification produced by a mirror.

Snell's law.

Lens formula.

Magnification produced by a lens.

Power of a lens.
