Answer:

frequency of light = $4.2\times 10^{-13}$

Explanation:

we know that relation between frequency and wavelength of light is

frequency × wavelength = speed of light.

therefore frequency = $\frac{c}{wavelength}$

= $\frac{3\times 10^{8}}{6.98\times 10^{-6}}$

= $4.2\times 10^{-13}$

For any given element the mass number can be found by adding the protons and the neutrons.

In this case its 10 protons plus 11 neutrons which gives us 21 as the mass number.
