What are the images of the eyepieces and objective lenses of microscopes and telescopes?
The objective of a microscope produces a magnified inverted real image, the eyepiece of a microscope produces a magnified upright virtual image, and the final image of the microscope is a magnified inverted virtual image; The objective of the telescope is an inverted reduced real image, the eyepiece of the telescope is an upright magnified virtual image, and the telescope ultimately forms an inverted magnified virtual image.
A telescope is an optical system that uses an objective lens and eyepiece to keep the incident parallel light beam parallel and emitted. According to the telescope principle, there are three types. The instrument that observes electromagnetic radiation from distant objects by collecting electromagnetic waves is called a radio telescope.
In daily life, telescopes mainly refer to optical telescopes. But in modern astronomy, astronomical telescopes include radio telescopes, infrared telescopes, X-ray and gamma ray telescopes. The concept of astronomical telescopes has further expanded to the fields of gravitational waves, cosmic rays, and dark matter.
A microscope is mainly composed of an eyepiece, objective lens, stage, and reflector. The eyepiece and objective are convex lenses with different focal lengths. The focal length of the objective convex lens is smaller than that of the eyepiece convex lens. The objective lens is equivalent to the lens of a projector. This object is inverted and magnified through an objective lens. The eyepiece is equivalent to a regular magnifying glass, which creates a magnified virtual image of the real image through the eyepiece.,
