A monochromatic beam of light is absorbed by a collection of ground-state hydrogen atoms in such a way that three different wave

lengths are observed when the hydrogen relaxes back to the ground state.
Physics

Answer:

If the absorbed beam is monochromatic (one wavelength) then it excites the H atom to some state n.

When that state decays, some of the atoms may decay to state 1, others to state 2, and still others to state 3

The net energy emitted in such a case would depend on:

n -1, n - 2, n - 3 which would produce 3 different wavelengths

How can we describe, model, and explain the material world, and are there limitations?
taurus [48]

Answer:· A model is a description of natural phenomenon that scientists can use to make predictions. A good model is both as accurate as possible and as simple as possible, which makes it not only powerful but also easy to understand. However, no matter how good they are, models will almost always have limitations.
