A beam of white light is incident normally on a plane surface absorbing 70% of the light and reflecting the rest. If the incident beam carries 20 W of power, find the force exerted by it on the surface. A beam of white light is incident normally on a plane surface absorbing 70% of the [...]

Ionization energy of a hydrogen-like ion A is greater than that of another hydrogen-like ion B. Let, r, u, E and L represent the radius of the orbit, speed of the electron, energy of the atom and orbital angular momentum of the electron respectively. In ground state E and L represent the radius of the [...]

Figure shows the intensity-wavelength relations of X-rays coming from two different Coolidge tube. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is V_A and the atomic number of the target material is ZA. These quantities are Vβ and Zβ for the other [...]
