This allows the viewer to see an image more clearly, with "sharpness of image".
What is resolution.
500
Explain how a microscope magnifies an image. Use some of the key terms we learned in the chapter.
--------------------------------------------------------------------
Explain how a convex lens bends light.
A microscope magnifies an image by bending the light that passes through a convex lens and shines on the specimen.
-----------------------------------------------------------------
A convex lens is thicker in the center than at the edges. The light is curved as it is focused to a single point, magnifying the image.
