How do negatively charged plates affect the path of cathode rays?
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
What did JJ Thomson's cathode-ray tube experiment show?
Thompson observed that these rays are negatively electrically charged.
When Thomson held a positively charged plate near the cathode ray the beam bent toward the plate What conclusion can be drawn from this observation?
The cathode "ray' must have been made up of negatively charged particles, now called electrons.
Why cathode rays are negatively charged?
Cathode rays are produced when the metal cathode has a high voltage applied to it - this has the effect of "boiling" the electrons off the cathode's surface producing cathode rays, and so cathode rays can be seen as a stream of electrons i.e. negatively charged particles.AnswerElectrons are released from the surface of a cathode through thermionic emission. This is achieved by a heaterlocated at the cathode, and not due to a high voltage. The function of the high voltage (between the cathode and an anode placed closer to the screen) is to attract these electrons towards the screen of the CRT. So a 'cathode ray' is simply a beam of electrons which, of course, are negatively charged.
The behavior of cathode rays in a glass tube containing gas at low pressure led scientists to conclude that the rays were composed of?
Were composed of no charge particles .
Who discovered negatively charged electrons using a cathode ray tube?
JJ Thomson.
How did JJ Thomson know that the particles in the cathode-ray tube were negatively charged?
They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
Why did J Thomson reason that electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
How are cathode charged?
negatively charged
What did J J. Thomsons experiment show?
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
Which scientist discovered that cathode rays are made up of negatively charged particles?
English Physicist J.J. Thomson (1856-1940)
How do negatively charged plates affect the path of cathode rays?
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
How did J J Thomson show that cathode rays are different from light?
Thomson appreciated in 1897 that the cathode rays are formed from negative electrically charged very small particles. These particles are the electrons. From this Thomson concluded that the atom is not indivisible and also that the atom must contain and a positive charged particle.

What is a Cathode ray gun?
basically JJ Thomson wanted to find out what a cathode ray was made of. Cathode tubes are a tube with wires in them. Scientists discovered that if the created a vacuum in the tube and sent a charge through the wires, it glowed. JJ Thomson set up a cathode ray and placed magnets on either side. This deflected the ray so the tube didn't glow. This meant the rays were negatively charged which meant they were made of negatively charged particles or electrons.
