when an electron in hydrogen atom jumps from third excited state to the ground state how would the de - Broglie wavelength associated with the electron change?Very urgent tomorrow exam.
Use the rudberg's formula
1/lambda=1/R*[1/n12 - 1/n22]
where n1=1 and n2=3.
you would get lambda=9R/8
1/lambda=1/R*[1/n12 - 1/n22]
where n1=1 and n2=3.
you would get lambda=9R/8
