The emission spectrum of the element lithium is shown below.

what is the best estimate of the color that will be seen when a sample of lithium gas absorbs a lot of energy?

mix of blue and green
mix of red and orange
mix of yellow and green
pure yellow

mix of red and orange

Explanation:

The lithium emission spectrum indicates high intensity at the wavelength of 600nm to 700nm

In the visible light spectrum, colors that are in this range are;

Red=700 - 630 nm

Orange= 630 to 590nm

A sample of lithium gas that has absorbed a lot of energy will show  a mix of red and orange colors

a.) is the correct answer.
