Question

pls answer with explanation​

Answer 1

Answer:

Explanation:

In Lymann series, the ratio of minimum and maximum wavelength is 3/4 .

i.e... correct option is b) 3:4

Answer 2

Answer:

Correct option is 3/4

1/λ=R(1/n1²-1/n2²)

Lyman series: n1=1

Shortest wavelength, n2=∞

1/λ=R(1/1²)=R

Largest wavelength: n2=2

1/λ=R(1/1²−1/2²)=3R/4

Ratio = 3:4
