Worked Solution & Example Answer:When using a light microscope, magnification of the structure being observed can be increased by a variation in the A - VCE - SSCE Biology - Question 2 - 2005 - Paper 1
Step 1
Determine the factor that increases magnification
Answer
To determine which factor contributes to the increase in magnification when using a light microscope, we must analyze the options provided:
- A. light intensity: While adjusting light intensity can enhance visibility, it does not increase magnification.
- B. stage position: The position of the stage can affect focus but not magnification directly.
- C. objective lens power: This option refers to the actual lens used for magnification. Increasing the power of the objective lens directly increases the magnification of the object being observed.
- D. iris diaphragm setting: This controls the amount of light entering the microscope but also does not affect the magnification itself.
Based on this analysis, the best choice that increases magnification is C. objective lens power.
