Question

8 The peak emission from a black body at a certain temperature occurs at a wavelength of 6000A On increasing its temperature the total radiation emitted is increased to 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 a 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 r eV where r is the numerical constant The value of r is found out to be ical cons 1 The value of r is found out to be 537 fi 53p find the 100 value of p Take he 12429 1
