Discovery of Sub-Atomic Particles Flashcards
Which scientist studied electrical discharge in partially evacuated tubes called Cathode Ray Tubes?
Faraday
Which scientist studied electrical discharge in partially evacuated tubes called Cathode Ray Tubes?
Faraday
Why a gas of low pressure was used in the Cathode Ray Experiment?
Since there is enough space between gaseous atoms, It can accelerate and strike another atom creating positive charges and free electrons
Name the phosphorescent coating on the tube behind the anode that confirmed Cathode Rays
Zinc Sulphide
When do Cathode rays produce X-Rays?
When they strike Tungsten and Molybdenum
How can we confirm that rays travel in a straight line in the absence of magnetic and electric fields?
Formation of shadow when an object is placed between
How can we conclude that cathode rays contain mass and velocity?
They rotate the paddle wheel placed in their path
Deviation of electrons depends upon_____
Charge, Mass and Strength of Fields
What did Milikan discover?
Q=ne
Is the q/m ratio of Canal Rays the same for all atoms? In which atom is its highest?
No. Hydrogen
