Frequently Asked Questions (FAQs) on Optical Instruments
What are optical instruments?
Optical instruments are devices that utilize the properties of light to observe, manipulate, or measure objects and phenomena. They include tools such as microscopes, telescopes, cameras, binoculars, spectrometers, and lasers.
What is the function of a microscope?
Microscopes are used to observe objects that are too small to be seen with the naked eye. They magnify the image of specimens using lenses or a combination of lenses and light sources.
How does a telescope work?
Telescopes gather and focus light from distant objects to produce magnified images. They use lenses or mirrors to collect and concentrate light, allowing astronomers to observe celestial bodies such as stars, planets, and galaxies.
What is the focal length of a telescope?
The focal length of a telescope is the distance (mm) inside the optical system between the lens or primary mirror to the point where the telescope is in focus. This point is called the focal point.
Why are converging lenses used?
Converging lens are used to make things appear larger .
Why are diverging lenses used?
Diverging lenses are used to make things appear smaller .
Optical Instruments
Optical instruments are devices designed to manipulate and detect light for various purposes, ranging from imaging to measurement and analysis. They utilize the principles of optics, which is the branch of physics that deals with the behavior and properties of light.
In this article, we will study about optical instruments, different types of optical instruments such as eye, lens, microscope, telescope, periscope, and kaleidoscope, and their working.
