VB) Only (P) and (Q) are correct
(C) Only (Q) and (R) are correct
(D) Only (P) and (R) are correct​

Answer 1

Answer:

It can focus and it hss convex lense.

Explanation:

Option (B) is correct. The microscope is used to focus and enlarge small or micro things to a level where a naked eye can clearly see that thing. The convex lens is used for that purpose because it absorbs all the rays and focuses them on one point to make a clear image. We can see the nanoparticles through it as well. It makes the object (10×), that is 10 times greater than its original size.
