Question

all formula of 10th physics chapter light reflection and rarefaction

Answer 1

Formula related to spherical rmirror
1. F= r/2
2. 1/v +1/u=1/f
3. m=height of image /height of object
Formula related to lens
For thin lens
1/v-1/u=1/f
Magnification by a thin lens
m=height of image /height of object=v/u
Power of thin lens =P=1/f
