If it's a *Crookes* tube you're asking about, it's a discharge tube because the applied electrical field causes ionization and a resulting discharge of energy in the form (mostly) of light, depending on the gas or gases in the tube.
Because the tube is hollow
discharge tube can be used for indentifying electrons while tube light cxannot
A longer tube causes the soundwave to have a longer wavelength, a lower frequency and hence have a lower pitch.
yes
Blowing in the mouthpiece over the reed causes it to vibrate. This causes sound waves that travel down the body of the clarinet. The more holes you close off on the keys, the longer the tube of the clarinet is and the lower the note.
argon is blue in discharge tube
Ddischarge tube led to the discovery of Cathode rays (electrons) and Positive rays (protons) so this discovery of cathode rays and positive rays can be considered as conse quences of discharge tube.
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.
He is a scientist who modified and experimented with discharge tube

The orifice tube is located in the line at the condenser discharge connection.
