Is this wavelength in vacuum?
Answer; as per mass of CPH is constant, and Vc is for an alone CPH, so wavelength should be in vacuum, that there is not any gravity effect. But it never happens.
The width of the central bright band of a diffraction pattern is 2.9 cm. Laser light of unknown wavelength passes through a single slit that is 0.042 mm wide and onto a screen
A Plane polarized light is incident on a piece of quartz cut parallel to its axis. Evaluate the least thickness for which ordinary ray and extraordinary ray combine
Molecules: Let us take a piece of matter, for example, a drop of water and see what happens when it is sub-divided into smaller and smaller portions. The drop is first cut
Potential at a point in a field is described as the amount of work done in bringing a unit positive test charge; from infinite to that point along any arbitrary path. Electric pote
