Gas Discharge Tubes: Exploring the World of Spectroscopy

What is a tube filled with gas through which electricity is passed called?

a) a spectrophotometer

b) a spectroscope

c) a gas discharge tube

d) an atomizer

Answer:

The correct answer is c) a gas discharge tube.

If you chose option c) a gas discharge tube, you are absolutely correct! A gas discharge tube is a fascinating device that is used in various scientific applications, particularly in spectroscopy.

When an electric current is passed through a gas discharge tube filled with a specific gas, it causes the gas to emit light of distinct wavelengths. This emitted light can be observed, studied, and analyzed to gain insights into the properties of the gas and its spectral characteristics.

Gas discharge tubes play a crucial role in the field of spectroscopy, allowing scientists to explore the unique patterns of light emitted by different gases under specific conditions. They are also utilized in lighting technologies and other scientific experiments where controlled emission of light is desired.

By understanding the principles behind gas discharge tubes, we can delve deeper into the world of spectroscopy and uncover the hidden secrets of light and matter. So, next time you encounter a gas discharge tube, remember the magical interplay between electricity and gas that illuminates the world of science!
