Question

write all the formulas of chapter
light-reflection and refraction

ALL FORMULA

Answer 1

Mirror

1/f=1/v+1/u

-v/u=m

h'/h=m

-v/u=h'/h

Lens

1/f=1/v-1/u

v/u=m

v/u=h'/h

Answer 2

☺here is your answer dear☺

$focal \: length \: = \frac{r}{2} \\ \\ \frac{1}{v} + \frac{1}{ u} = \frac{1}{f} \\ \\ m = \frac{v}{u} \\ \\ snell \: law \: = \frac{sin \: i}{sin \: r} \\ \\ n = \frac{c}{v} \\ \\ n = \frac{1}{sin \: c} \\ \\ \frac{1}{v} - \frac{1}{u} = \frac{1}{f} \\ \\ p = \frac{1}{f} \\ \\ p = p1 + p2 + p3 + ...... \\ \\ m = m1 \times m2 \times m3 \times ......$
HOPE IT HELPS YOU DEAR
