Wavelength of radiations emitted, when an electron jumps from a state A to C is 2000 Å and it is 6000 Å, when the clectron jumps from state B to state C. Wavelength of the radiations emitted, when an electron jumps from state A to B will be:

Answer»

2000 Å
3000 Å
4000 Å
6000 Å

Solution :USE `lambda_(3)=(lambda_(1)+lambda_(2))/(lambda_(1)+lambda_(2))`
Here `lambda_(3)=2000Å, lambda_(1)=6000Å," then "lambda_(2)=3000Å`
