1. In figure, the energy level of Hydrogen is shown. Three steps and are also shown due to transition of electron as a photon of wave length is ejected from any of them.
2.
In the figure, a cycle is shown with the graph
Here, the temperature at
The molar specific heat at constant volume
Number of mole 1.6, and .
3. Three metalic plates of and are used in the photoelectric effect. The work functions of them are and respectively. Light having same intensity of wave length of and respectively be incident of them individually and the value of photoclectric effect was examined.
4. Light of wave length used in Young's double slit experiment and the width of fringe found in air. Later on the position of fringe with the wave length of light of and respectively was observed.
5.
The given transistor of the figure is used to amplify the signal of . If the signal is connected to the input then the charge in the flow of current of the base is .
