Mercury's atomic emission spectrum is shown below. estimate the wavelength of the dark green line. what is its hz what is the energy of an dark green photon emitted by the mercury atom?

Explanation:

From the atomic emission spectrum of Mercury, the wavelength of the dark green line is 545 nm.

The relation between the frequency and wavelength is given by :

Let E is the energy of an dark green photon emitted by the mercury atom. It is given by :

h is Planck's constant

Hence, this is the required solution.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
