Are cathode rays electromagnetic waves?
Cathode rays are not electromagnetic rays because the cathode ray is a beam of electrons that travel from the negatively charged to positively charged end of a vacuum tube, across a voltage difference between the electrodes placed at each end.The electrode at the negative end is called a cathode; the electrode at the positive end is called an anode.Since electrons are repelled by the negative charge, the cathode is seen as the "source" of the cathode ray in the vacuum chamber.
What is on the cover of Calculating Infinity album by The Dillinger Escape Plan?
It's a cathode from a very old cathode ray tube. It is the far end part of an old television cathode ray tube (used in other machines than television too).
Why is you tube called youtube?
You is obvious. YOU control the content. Tube may be in reference to the old monitors, the cathode ray TUBE monitors.
What instrument measures frequency?
a frequency counterIt all depends on what you're measuring the frequency of. From what I have found, you need either a frequency counter, or if it's sound, a CRO(cathode ray oscilloscope), but a high quality one is extremely expensive, or if you have an iPod touch/iPhone and headphones with a mic, just get an app for it.Gladometer
Is ray ray ugly?
ray ray is no where ugly :)
Stream of electrons produced at the negative electrode of a tube containing a gas at a low pressure?
cathode ray
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
What observation did Thomson make to suggest that an electron has a negative electric charge?
The deflection of cathodic rays was the source of inspiration for Thomson.
Differentiate between anode ray and cathode ray?
Anode ray is positive and cathode ray is negative
How did William Crookes determine the nature of the beam in cathode ray tube?
In his investigations of the conduction of electricity in low pressure gases, William Crookes discovered that as the pressure was lowered, the negative electrode (cathode) appeared to emit rays (the so-called cathode rays, now known to be a stream of free electrons, and used in cathode ray display devices).

Difference between direct and indirect cathode ray?
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
What prompted early scientists to propose that the ray of the cathode ray tube was due to the cathode?
The electron had already been discovered. It took little imagination to "see" that the cathode ray was the beam of electrons that originated from the cathode. And the beam was controlled using techniques based directly on what was correctly understood about the electron. The cathode ray could only be an electron beam generated at the cathode. Conventional elctric current flow is usually thought of as flowing from positive to negative, but at the quantum level; due to electrons having a negative charge; technically they really flow from negative to positive, and this is apparent in the cathode ray tube. Its the negatively charged electrons that glow in a cathode ray tube, and do so from the negative terminal, or cathode, hence the name.
What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
What are the rays in the cathode ray tubepositive or negative or neutral?
The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.
What observations did Thomson make to suggest that an electron has negative electric charge?
Thomson observed that a cathode ray bent when in the presence of a magnetic field. After the cathode ray bent the opposite way when the opposite pole of the magnet was placed next to it, Thomson concluded that the cathode ray had a negative charge.
What did the Cathode Ray do?
Cathode rays (also called an electron beam or e-beam) are streams of electrons observed in vacuum tubes, i.e. evacuated glass tubes that are equipped with at least two metal electrodes to which a voltage is applied, a cathode or negative electrode and an anode or positive electrode.
