Final answer:
The total magnification of a microscope using an ocular lens with a magnification of 5x and an objective lens with a magnification of 40x is 200x.
Step-by-step explanation:
To calculate the total magnification of a microscope, you simply multiply the magnification of the ocular lens by the magnification of the objective lens. In the case of an ocular piece with a magnification of 5x and an objective lens that is 40x, you would perform the following calculation:
- Ocular magnification: 5x
- Objective magnification: 40x
- Total magnification: 5x × 40x = 200x
This means that the total magnification provided by this microscope when using these lenses is 200 times the actual size of the specimen being viewed.
