The equation of which of the below scientists could be used to find the wavelength of the emission lines of the hydrogen atom:
mihalych1998 [28]

The equation that scientists could use to find the wavelength of the emission lines of the hydrogen atom would be that of Balmer.

The wavelength of the emission lines of the hydrogen atom can be derived using the Balmer series:

        1/λ  = R_H (1/4 - 1/n^2)

Where λ = wavelength, R_H = Rydberg constant, and n = level of the original orbital.

The equation becomes applicable in getting the wavelength of emitted light when electrons in hydrogen atoms transition from higher (n) orbital to lower orbital (2)  levels.

More on the Balmer series can be found here: brainly.com/question/5295294

What is happening to the temperature of the substance BEFORE AND AFTER the phase changes?
Neporo4naja [7]
First off, you must realize that the phase changes are marked by the points B and D on the graph. They are level because all of the energy (or heat) being added is being consumed by the physical process. So The temperature is increasing before the phase change, and after the phase change. The moments before and after are represented by points A, C, and E.
