B. the amount an object is enlarged CORRECT ANS >> A
3. Most light microscopes carry a light filter CORRECT ANS >> blue
4. Why do light microscopes have a blue light filter?


A. to filter out blue light, leaving more red light, which is best for highest
resolution images

B. to make the light easier on the eye, while being on the microscopes for long
periods of time
