The energy levels of an atom are as shown in Fig.1.23 Which transition corresponds to emission of radiation of maximum wavelength? .

If wavelengths of two radiations are in the ratio of 1:2 , then the ratio of energy of corresponding photons is 1:1 2:1 4:1 3:2

The peak emission from a black body at a certain temperature occurs at a wavelength of 6200 A. On increasing its temperature, the total radiation emitted is increased 16 times. These radiations are allowed to fall on a metal surface. Photoelectrons emitted by the peak radiation at higher temperature can be bought to rest by applying potential equivalent to the excitation potential corresponding to the transition for the level n=4 to n=2 in the Bohr's hydrogen atom. The work function of the metal is given by alpha/100 eV where alpha is the numerical constant. Find the value of alpha.

For a certain atom, there are energy levels A, B, C corresponds to energy values E_A Choose the correct option if lamda_1,lamda_2,lamda_3 are the wave length of radiations corresponding to the transition from C to B, B to A and C to A respectively. .
