The difference in potential between the two Ds of a cyclotron accelerate the particles across the gap. The direction of potential difference switches every half cycle to keep the particles accelerating. T...
Conduction is the transfer of heat caused by the collision of particles inside a substance and between substances. In order to reduce heat loss, some thermos flasks have a vacuum between ...
The path upon which light propagates is determined by Fermat's Principle. This says that light will always travel along the path of least time. Now, we often think of the speed of light as a constant, but...
In our situation, the stopping potential doesn’t let any electron to pass. When we increase the frequency of incident light, the electrons get more energy. We know it from equation E=hf. When electrons ga...
As the proton number increases by 1 from 19(K) to 20(Ca), the process of decay must be beta minus in order to conserve charge. This means that an electron (or beta plus particle) will be emitted along wit...
