Question

12.
The shortest wavelength for the Lyman series is .... (Given R = 109678 cm');
(1) 911 Å
(2) 700 Å
(3) 600 A​

Answer 1

Answer:

The shortestwavelength for the Lyman series is 911A

Answer 2

Answer:

911 Angstorm.

Explanation:

For Lyman series n1=1

For Lyman series n1=1For shortest λ of Lyman series; energy difference in two levels showing transition should be maximum i.e n2=∞

1/λ=RH[1/1^2−1/∞^2]

1/λ=109678

λ=911.7×10^−8cm

λ=911.7×10^−8cm=911.7A∘
