Question

The first three energy levels of the fictitious element X are shown below. E (eV) --------------------- n=3 ----------> -2.0 n=2 ----------> -3.0 n=1 ----------> -6.5 What wavelengths are observed in the absorption spectrum of element X? What wavelengths are observed in the emission spectrum? An electron with a speed of 1.8x10^6 m/s collides with an atom of element X. Shortly afterward, the atom emits a 1280 nm photon. What was the electron's speed after the collision?

Step 1

To find the wavelengths observed in the absorption spectrum of element X, we need to consider the possible transitions of electrons from lower energy levels to higher energy levels. The possible transitions are: a. n=1 to n=2 b. n=1 to n=3 c. n=2 to Show more…
