Question

microscopes use lenses to __ the image of an object by . types of microscopes include: 1) allow light to pass through a specimen and uses two lenses to form an image. - they produce clear images only to a magnification of about . - they can view specimens. 2) use beams of electrons that are focused by magnetic fields. two types of electron microscopes are: a) microscopes make it possible to explore cell structures and large protein molecules. - they can only be used with specimens. b) microscopes use a pencil - like beam of electrons to scan over the __ of a specimen. - they produce three - dimensional images.

Explanation:

Microscopes magnify images. Light microscopes use light and two - lenses, good for living specimens up to a certain magnification. Electron microscopes use electron beams. Transmission electron microscopes are for exploring cell structures and need non - living specimens. Scanning electron microscopes scan the surface of specimens to produce 3D images.

Answer:

Microscopes use lenses to magnify the image of an object by bending light (or using electron beams in electron microscopes).

1. Light microscopes allow light to pass through a specimen and uses two lenses to form an image.

• they produce clear images only to a magnification of about 1000x.
• they can view living specimens.

1. Electron microscopes use beams of electrons that are focused by magnetic fields.

A) Transmission electron microscopes make it possible to explore cell structures and large protein molecules.

• they can only be used with non - living specimens.

B) Scanning electron microscopes use a pencil - like beam of electrons to scan over the surface of a specimen.

• they produce three - dimensional images.
