Question

1. When rubidium ions are heated to a high temperature, two lines are observed in its line spectrum at wavelengths (a) 7.9 × 107 m and (b) 4.2 × 107 m. What are the frequencies of the two lines

Answer 1

`b. \: frequency = \frac{3 * 10 {}^( 8) }{4.2 * 10 {}^(7) } = (50)/(7) = 7.14 \: hz`

`a.frequency \: = \frac{3 * 10 {}^(8) }{7.9 * 10 {}^(7) } = (300)/(79) = 3.8 \: hz`
