Question

Calculate the no.of red coloured lines when electron jumps from fifth orbit to ground state

Answer 1

Answer:

assuming hydrogen atom

E5-E1=hU

(-13.6÷25+13.6÷1)*1.6*10^-19=6.62*10^-34*u

frequency u=3.155×10^15

c=u*lambda

3*10^8=3.155×10^15*lambda

lambda=9.507×10^-8 m

lambda=950 A

emitted light it in infrared region

hence no red line will be seen
