How far can sound travel through a tube?
Sound cannot travel forever.E.g, When someone is talking and there are lots of people around can't here them. This is because when you speak it causes the air molecules in front to bump into the air molecules in front of it to bump in to the other bunch, etc. This is how sound waves are are made.
How does a tube produce sound?
A tube produces sound by allowing air molecules to vibrate within it. When air is forced through the tube, it creates pressure differences that cause the air molecules to move back and forth, creating sound waves. The length and shape of the tube determine the pitch and tone of the sound produced.
Who invented the vaccum tube?
The vacuum tube was invented by Thomas Edison in the late 19th century. However, it was not until Lee de Forest's modification in 1906 that the vacuum tube became an essential component in early electronics.
Which type of motion does cathode rays create?
Cathode rays create straight-line motion. They are streams of electrons that travel in a straight line from the cathode to the anode in a vacuum tube.
What is a vacuum discharge tube?
A closed vessel having electrodes at either end and containing agas at low pressure. When a sufficient voltage is applied to theelectrodes, an electric current flows through the gas. Dischargetubes can be used to prevent current flow below a certainvoltage; they can also function as lamps by the use of ionizinggas, which glows when current flows through the tube.
What is in a vacuum tube?
Millman's theorem
How does the sound travels through stethoscope tube?
Sound vibrates the bell (the part at the end), that vibrate the column of air in the tubing, this vibrate the earpiece and recreates the sound.
How far can sound travel through a tube?

What is the tube that sound waves travel along to get to the ear drum?
The auditory canal allows sound to get to the eardrum.
What computer component did the transistor replace?
the vacuum tube
Can soun travel through metal tube?
yes
What are the elements of a vacuum tube?
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
What are the Adavantages and disadvantages of vacuum tube?
when the vacuum sucks up things it goes through the tube and into the bag ...Unless you are talking about electronics, then a vacuum tube is used to form an amplifying circuit. Some tubes can emit cathode rays onto a screen (Cathode Ray Tube = CRT) to display a picture and some can function as diodes to regulate current flow.
Why is the cathode-ray tube in figure 4 connected to a vacuum pump?
A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.
What did Lee de Forest invent?
Lee de forest two major inventions were the vacuum tube,and sound for motion pictures
Where was vacuum tube was made?
