Microscope

Question 1

Magnification of simple microscope when image is forme at D

Answer 1

Md = 1 + D/f

Question 2

Magnification of simple microscope when image is formed at infinity

Answer 2

M = D/f

Question 3

Magnification of compound microscope when image is formed at D

Answer 3

M = -Vo/Uo ( 1 + D/fe)

L = Vo + Ue

Question 4

Magnification of compound microscope when image is formed at Infinity

Answer 4

M = -Vo/Uo x D/fe

L = Vo + fe
