Question

Which statement is true concerning the spectrum of hydrogen obtained from a gas discharge tube? a. A photon is absorbed as the electron goes from a state with a higher energy to one b. A photon is absorbed as the electron goes from a state with a lower energy to one c. A photon is emitted as the electron goes from a state with a higher energy to one d. A photon is emited as the electron goes from a state with a lower energy to one e. An electron is emitted as the photon goes from a state with a higher energy to on with a lower energy with a higher energy with a lower energy with a higher energy with a lower energy

Explanation / Answer

Answer is option (c): A photon is emitted as the electron goes from a state with a higher energy to one with a lower energy.

When electron goes from lower energy level to higher energy level - Photon (energy) is absorbed.
When electron goes from higher energy level to lower energy level - Photon (energy) is emitted.
A hydrogen discharge tube is a slim tube containing hydrogen gas at low pressure with an electrode at each end. If you put a high voltage across this, the tube lights up with a bright pink glow.
