Answers
Answer:
the working of telescopes and microscopes, colours in thin films etc, are explained in Optical physics
Explanation:
A telescope is an optical instrument which is used to see distant objects as magnified image. It magnifies the distant objects with the help of lenses, mirrors, etc. The most familiar telescope is optical telescope.
Microscope is an optical instrument which is used to see small objects that cannot be seen with the human naked eye. The meaning of microscope means invisible to eye. It also uses lenses to magnify objects. Visible light microscope or light microscope is the main used microscope.
In microscope, the eye piece lens magnifies image from objective lens. Eye piece can be moved with the help of turning wheel in it. In light microscope, the light from the mirror is reflected through the specimen. The image is produced from the objective lens. It can be magnified with the help of eye piece lens.
Different regions of film appear in different colors according to the thickness of films. Thin film interference occurs when light reflects multiple times. The colors are due to interference between light waves reflected from the top and the bottom surfaces of thin films. When light is incident on a thin film, the film appears colored
