Tutorial on L5-L6

L1 to L3 of Unit Measurement and Errors

The energies of three consecutive energy levels L_(3), L_(2) and L_(1) of hydrogen atom are E_(0), 4E_(0)/9 and E_(0)/4 respectively. A photon of wavelength lambda is emitted for a transition L_(3) to L_(1) . What will be the wavelength of emission for transition L_(2) to L_(1) ?

The energies of three conservative energy levels L_3,L_2 and L_1 of hydrogen atom are E_0 . (4E_0)/9 and E_0/4 respectively. A photon of wavelength lambda is emitted for a transition L_3 to L_1 .What will be the wavelength of emission for transition L_2 to L_1 ?

A bar magnet of length L is dropped inside a vertical copper pipe of length l(l lt L) , it will experience an acceleration q such that

The distance between two points P and Q is d and the lengths of projections of PQ on the coordinate planes are l_(1),l_(2),l_(3) then (l_(1)+l_(2)^(2)+l_(3)^(2))/(d^(2)

The bar chart represents number of fiction and non-fiction books in four libraries L_1 , L_2 , L_3 and L_4 comsider the bar chart and answer questions based on it. The ratio of total books of libraries L_1 and L_3 to L_2 and L_4 is
