1. Δv= h/4πx me x 10^-14
After substituting the values and simplifying
Δv= 5.8 x 10^9 m/s
2. 1st orbit
Thus v= 2.18 x 10^8
c= 3 x 10^8
So 3/x= 2.18
Thus x = 1.37
So v= c/1.37
5. d) n=4 l= 1
This indicates 4p orbital which has the highest energy amongst the 4.
3. En= E1 x z^2/n^2[1/n1^2-1/n2^2]
Replacing the values n1=1 n2=2
We get En= 1.635 x10^-18
Now E= hc/λ
So λ= hc/E
λ= 19.878 x 10^-26/1.635 x10^-18
λ= 1.214 x 10^-7
