FAQs on Optical Instruments: The Human Eye,Telescope & Microscope Video Lecture - Physics for JEE Main & Advanced
| 1. How does the human eye work to enable vision? |  |
Ans. The human eye works by allowing light to enter through the cornea, which then passes through the pupil and gets focused by the lens onto the retina. The retina converts the light into electrical signals that are sent to the brain via the optic nerve, where they are interpreted as images.
| 2. What are the main components of a telescope? | |
Ans. The main components of a telescope include the objective lens or mirror, which gathers and focuses light, and the eyepiece, which magnifies the image produced by the objective. There may also be additional components such as a mount, diagonal mirror, and finderscope.
| 3. How does a microscope magnify objects? | |
Ans. A microscope magnifies objects by using lenses to bend the light that passes through them. The objective lens collects light from the specimen and forms an enlarged image, which is then further magnified by the eyepiece lens. The total magnification is the product of the magnification of the objective and eyepiece lenses.
| 4. What is the difference between a compound microscope and a stereo microscope? | |
Ans. A compound microscope uses two sets of lenses to magnify specimens in 2D, making it suitable for viewing cells and other small objects. A stereo microscope, on the other hand, provides a 3D view of larger objects at lower magnification levels, making it ideal for dissection and inspection tasks.
| 5. How can the focal length of a lens affect the magnification of an optical instrument? | |
Ans. The focal length of a lens determines the distance at which it can focus light and affects the magnification of an optical instrument. A shorter focal length lens will produce higher magnification, while a longer focal length lens will result in lower magnification.
