QUESTION 1
In this context, the resolving power is a measure or capacity that objective lens has to resolve two points in the object that are very close between each other.
Note: According to Chegg’s guidelines, you have to send just one question. Please, send each question separate so all experts can answer each of your questions. Thank you!.
