What is the charge of the particle in cathode rays?

The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.


What would happen to the deflection of the cathode ray if the particle in the rays were heavier?

Why do cathode rays produce sharp shadow of object placed in their path?

Cathode rays produce a sharp shadow of an object because they travel in straight lines and can only pass through openings in obstacles. When an object is placed in the path of cathode rays, the rays are blocked by the object, creating a distinct shadow where the rays are unable to pass through. This phenomenon is due to the wave-particle duality of cathode rays.


Why cathode rays cast a shadow when an object is placed in their path?

Cathode rays are particles with mass and energy, which can be obstructed by solid objects in their path. When an object is placed in the path of cathode rays, the particles are blocked from passing through, creating a shadow on the opposite side of the object. This occurs because the object absorbs or scatters the cathode rays, preventing them from continuing in a straight line.


Why did Thomson see cathode rays with every element?

Thomson observed cathode rays with every element because cathode rays are composed of electrons, which are fundamental particles present in all atoms regardless of the element. When a high voltage is applied in a vacuum tube, electrons are emitted from the cathode and accelerate toward the anode, creating cathode rays. This universal presence of electrons in all elements allowed Thomson to consistently detect cathode rays across different materials. His experiments demonstrated that these rays were not dependent on the type of gas or metal used in the cathode.


Who discovered canal rays?

Canal rays were discovered by Sir William Crookes in 1870. He observed these rays while studying the behavior of cathode rays in a vacuum tube.


Why did Thomson see cathode rays with every elements tested?

Thomson observed cathode rays regardless of the element tested because cathode rays are composed of electrons, which are fundamental particles present in all atoms. When a voltage is applied in a vacuum tube, electrons are emitted from the cathode and travel toward the anode, creating the rays. This universality in the presence of electrons explains why he consistently saw cathode rays across different elements. Thus, the experiment demonstrated that electrons are a common component of all matter.


When did JJ Thomson discover the electron?

J.J. Thomson discovered the electron in 1897 while conducting experiments on cathode rays. He observed that these rays could be deflected by electric and magnetic fields, leading him to propose the existence of a negatively charged particle within the atom, which he named the electron.


How did Thomson determine that cathode rays are negatively charged?

Thomson observed that cathode rays were deflected by electric and magnetic fields in a manner consistent with them having a negative charge. He measured the charge-to-mass ratio of cathode rays and found it to be the same regardless of the material used for the electrodes, which suggested the charge was a fundamental property of the particles themselves.
