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.
A 1.25-kg box is being pulled across a level surface where μk is 0.80. If the string is suddenly cut, causing the applied force to immediately go to 0.0 N, what is the rate of
If either screen or source or both are at preset distance from the diffracting device (obstacle or aperture), the diffraction is known as Fresnel type.

A 2350-kg granite tombstone absorbs 2.8 x 107 J of energy from the Sun to change its temperature from 5.0°C at night to 20.0°C during an autumn day.
when do we use projected area instead of actual area and why
why wouldn''t you be electrocuted if you walked under an electric transmission line during a rainstorm?
An air stream is saturated with a vapor (B) at 130°F and 1 atm pressure. It is cooled down to 80°F where some of the B is condensed and separated from the vapor stream. The remai
Explain the Photoelectric Effect Atomic Models Heinrich Hertz first observed the photoelectric effect in 1887. He noticed that if a photon with enough energy is absorbed by an
