The Low Power Objective LensMagnification
= 4 x
Ocular magnification x Objective magnification
= Total Magnification
Eg. For the low power objective:
Ocular magnification x Objective magnification
Total Magnification = 10 x 4 =
4
Ocular magnification x Objective magnification
= Total Magnification
Eg. For the low power objective:
Ocular magnification x Objective magnification
Total Magnification = 10 x 4 = 40x
