When rubidium ions are heated to a high temperature, two lines are observed in its line spectrum at wavelengths (a) 7.9 × 10−7 m
svetlana [45]

Answer:

The frequencies of the two lines are:

a) 3.79\times 10^{14} s^{-1}

b)7.14\times 10^{14} s^{-1}

When we heat rubidium compound we will see red color.

Explanation:

\nu=\frac{c}{\lambda }

c = speed of light

\lambda = wavelength of light

a) Frequency of the light when wavelength is equal to 7.9\times 10^{-7} m

\nu=\frac{c}{\lambda }

\nu=\frac{3\times 10^8m/s)}{7.9\times 10^{-7}}

\nu=3.79\times 10^{14} s^{-1}

This frequency corresponds to red light

b) Frequency of the light when wavelength is equal to 4.2\times 10^{-7} m

\nu=\frac{c}{\lambda }

\nu=\frac{3\times 10^8m/s)}{4.2\times 10^{-7}}

\nu=7.14\times 10^{14} s^{-1}

This frequency corresponds to violet light

When we heat rubidium compound we will see red color.
