this is what i got- Scanning electron microscopes (SEM) are useful for studying the details of a specimen’s surface. The electron beam scans the specimen’s surface, which is coated with a thin layer of gold metal. The electrons that scatter off of the gold-coated surface are focused onto a screen, forming a detailed image of the specimen surface. The image is three-dimensional and black and white.
Its's between A or B
it's not A. The electron beam is scattered off the gold-coated surface, it doesn't pass through the specimen.
do you mean it's not B because B say it's passed not a?
oh, sorry. It is not absorbed by the specimen.
it is B, see how B talks about focusing the scattered electrons onto a screen?
therefore it's B?
yes if I were you, I would read this for awhile just for background knowledge
@sara1234 anything else you need help with?
