Fizeau method (A. Fizeau, 1851):
One of the first really relativistic experiments intended to calculate the speed of light. Light is flow through a spinning cogwheel driven through running water, is reflected off a distant mirror, and passed back then through the spinning cogwheel. While the rate of running water (and therefore the spinning of the cogwheel) is synchronized so that the returning pulses are eclipsed, c may be calculated.
velocity of sound is 330m/s and wavelength 1.5 m .With time interval of 1/1000 sec related phase difference will be
An electron in the hydrogen atom loses 3.02 eV as it falls to energy level E 2 . From which energy level did the atom fall?
All solar cells require a light absorbing material contained within the cell structure to absorb photons and generate electrons via the photo voltaic effect. The materials used in
What is a neutron? A neutron is a subatomic particle. Neutron is one of the building blocks of the atom. It has a mass of about 1.675 x 10-27 kg. Its spin is + 1/2 and that
