WebbCourse: Class 12 Physics (India) > Unit 9. Lesson 8: Optic instruments: telescopes and microscopes. Human eye: accommodation and near point. Power of accommodation. … WebbA microscope with a high resolution and uses two sets of lenses providing a 2-dimensional image of the sample. The term compound refers to the usage of more than one lens in the microscope. Also, the compound microscope is one of the types of optical microscopes. The other type of optical microscope is a simple microscope.

Webb4 okt. 2024 · A simple microscope is a magnifying glass that has a double convex lens with a short focal length. Examples of this kind of instrument include the hand lens and reading lens. When an object is kept near the lens, then its principal focus with an image is produced, which is erect and bigger than the original object. Webb6 okt. 2024 · Class 12th Physics wave optics ppt 1.

When light ray undergoes refraction, there is a change in its velocity and wavelength but frequency of the light does not change. V 1 –velocity of light in 1 medium. V 2 – velocity of light in 2 medium. λ 1 - wavelength of light in 1 ... WebbThe magnifying power of a microscope is given by. m = 1+ D f. where f is the focal length of the lens and D is the least distance of distinct vision for the normal eye. The magnifying power of a microscope can be increased by using a lens of short focal length. But it cannot be increased indefinitely. irish bardic poetry
