Question

Q267) The wavelength of radiation emitted, when in He+ electron falls from infinity to stationary state would be (R = 1.097 × 10^{7} m^{–1})

Q267) The wavelength of radiation emitted, when in He+ electron falls from infinity to stationary state would be (R = 1.097 × 10

SOLUTION

Z =2 , n_{1}= 1 and n_{2} =∞

Onsubstituting above values in equation
λ = 2.2 × 10^{–8} m

Answer:(a)
