Passage VII
According to a simplified model of the hydrogen atom, an electron orbits a proton located at the center of the atom. The electron can exist only in certain orbits, each with a specific radius. When the electron jumps from one orbit to another orbit of smaller radius, the atom emits a packet of energy known as a photon.
The electron jumps shown in Figure 1, which involve the first 6 orbits, result in the emission of 3 types of photons—ultraviolet, visible, and infrared. The energies and wavelengths of the photons emitted due to these jumps are shown in Table 1.

39. According to Figure 1, if the electron in a hydrogen atom jumps from Orbit 6 to Orbit 3, and then jumps from Orbit 3 to Orbit 1, the atom will emit:
Your Answer is
Correct Answer is C
Explanation
According to figure 1, the infrared photon will be released from Orbit 6-Orbit 3;
The ultraviolet photon will be released from Orbit 3-Orbit 1, so choose C
