Question

complete the calculations for total magnification produced by various combinations of the eyepiece and objective lenses. remember, to calculate the total magnification achieved when using a particular objective, multiply the power of the eyepiece by the power of the objective used.

1. when the scanning (4x) objective is used the total magnification will be (click to select)
2. when the low power (10x) objective is used the total magnification will be (click to select)
3. when the high power (40x) objective is used the total magnification will be (click to select)
4. when the oil immersion (100x) objective is used the total magnification will be (click to select)

Explanation:

Step1: Assume eyepiece power is 10x

Let the power of eyepiece $E = 10$.

Step2: Calculate for 4x objective

For a 4x objective ($O_1=4$), total magnification $M_1=E\times O_1 = 10\times4=40$.

Step3: Calculate for 10x objective

For a 10x objective ($O_2 = 10$), total magnification $M_2=E\times O_2=10\times10 = 100$.

Step4: Calculate for 40x objective

For a 40x objective ($O_3=40$), total magnification $M_3=E\times O_3=10\times40 = 400$.

Step5: Calculate for 100x objective

For a 100x objective ($O_4 = 100$), total magnification $M_4=E\times O_4=10\times100=1000$.

Answer:

1. 40
2. 100
3. 400
4. 1000
