Question

after switching from the high - power to the low - power objective lens of a compound light microscope, the area of the low - power field will appear
1 larger and brighter

1. smaller and brighter
2. larger and darker

4 smaller and darker

Explanation:

When switching from high - power to low - power objective lens in a compound light microscope:

• Field of view size: Low - power objective lens has a larger field of view compared to high - power. So the area seen is larger.
• Brightness: Low - power objective lens allows more light to enter the microscope (because the magnification is lower and the lens gathers light over a relatively larger area for the same specimen illumination source). So the image is brighter.

Answer:

1. larger and brighter
