Compton effect (A.H. Compton; 1923)
An effect which demonstrates that photons (the quantum of electromagnetic radiation) contains momentum. At a stationary particle, a photon fired such as an electron, will impart momentum to the electron and, as its energy has been reduced, will experience a corresponding falling in frequency.
principle and working of compound microscope
Que: What is an electric current? Answer: From Ohm's Law V = IR amid R being a constant one finds that I = V/R. therefore current is equal to voltage divided by resis
In a young's double slit experiment a point on the screen is similar distance from both the slits if any one of the slit is closed the intensity at P due to the other slit is 0.02

which electronic level would allow the hydrogen atom to absorb a photon but not to emit a photon
Q. What does the MeV in MeV photon mean? Answer:- The MeV denotes million electron volts. It's a calculation of the energy the energy in the photon which is a quantum (or
Stefan-Boltzmann constant; sigma (Stefan, L. Boltzmann) The constant of proportionality exist in the Stefan-Boltzmann law. It is equivalent to 5.6697 x 10 -8 W/m 2 /K 4 .
A point is operating simple harmonic motion with a time period 2πs. At its mean position its speed is 0.05 m/s. Calculate its speed when it is at a distance of 0.04 m from the mean
