In a compound microscope, the magnification by objective = 20, magnification by eyepiece = 11, then the total magnification is
- A
M = -220
- B
M = -0.19
- C
M = -0.05
- D
M = 220
The explanation is given below:
To find the total magnification of two lenses combined we must multiply individual magnifications:
20x11 = -220
This option is incorrect as per the formula.M = M_{objective} \times M_{eyepiece}
Given:
M_{objective} = 20
M_{eyepiece} = 11
Therefore, the total magnification is:
M = 20 \times 11 = 220
This option is incorrect as per the formula.M = M_{objective} \times M_{eyepiece}
Given:
M_{objective} = 20
M_{eyepiece} = 11
Therefore, the total magnification is:
M = 20 \times 11 = 220
This option is incorrect as per the formula.M = M_{objective} \times M_{eyepiece}
Given:
M_{objective} = 20
M_{eyepiece} = 11
Therefore, the total magnification is:
M = 20 \times 11 = 220
This option is correct.
To find the total magnification of two lenses combined we must multiply individual magnifications:
20x11 = 220
