Name one disadvantage of light microscopes

Limitations
Light microscopes can magnify specimens or objects up to fifteen hundred times their actual size. This is amazing if you consider objects naturally visible to the eyes. But when you consider microscopic specimens then the magnification is not very impressive. Also the depth of field is confined. For very specific observations of elements or specimens that are smaller than 0.275 microns or smaller than half the wavelength of white light require electron microscope.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
