A team of researchers is studying the external structures on the dorsal (back) surface of a spider mite.The spider mite seems to be the habitat of an even smaller mite,which is approximately 0.05mm.While they can see the dorsal surface of the spider mite with their naked eye,they cannot see the mite clearly.The researchers are writing a grant to provide support for a microscope to use to study these new mites.They need to purchase a microscope with a high magnification to observe the new mites on their habitat.Based on the information given,what type of microscope would you suggest?
