To calculate the total magnification of a microscope, you multiply the magnification power of the ocular (eyepiece) lens by the magnification power of the objective lens being used.
1. For the objective lens set to 40x:
\[ \text{Total Magnification} = \text{Ocular Magnification} \times \text{Objective Magnification} \]
\[ \text{Total Magnification} = 30x \times 40x = 1200x \]
2. For the objective lens set to 10x:
\[ \text{Total Magnification} = 30x \times 10x = 300x \]
As for the statement regarding the compound microscope:
When using a compound microscope, light must be able to pass through the specimen being examined.
- **True**: In most cases, a compound microscope is designed to allow light to transmit through the specimen, especially for biological specimens that are thin enough for light to pass through.
