What are the properties of cathode rays class 11?

What are the properties of cathode rays class 11?

Property 1: Cathode rays travel in a straight line and they can cast sharp shadows. Property 2: They are negatively charged. Property 3: Electric and magnetic fields deflect cathode rays. Property 4: They are produced at the cathode and travel to the anode in a vacuum tube.

What are the properties of anode rays class 11?

• All of these.
• Following are the properties of anode rays:
• 1) Anode rays deflect towards negatively charged plate.
• 2) Anode rays travel along a straight path in absence of electric and magnetic field.
• 3) Anode rays are positively charged radiations due to positive charged sub-atomic particles.

What are cathode rays and anode rays class 11?

Cathode Rays	Anode rays
They are starting from the cathode and travelling towards the anode	They are starting from anode and move towards cathode.
The anode is in the form of a regular electrode	The cathode is having a hole in it and anode rays are passing through it. Hence they are called as canal rays

How were cathode rays discovered Class 11?

In 1858, Plücker discovered cathode rays by sealing two electrodes inside the tube, evacuating the air and forcing it between the electrode’s electric current.

What are the 4 properties of cathode rays?

Some properties of cathode rays:

• They travel in a straight path.
• They have a negative electric charge.
• They have particle property.
• Magnets can deflect them.
• Charge/mass ratio of the rays is constant.
• They travel from the cathode to the anode.

What are the characteristics of Canal Rays Class 11 chemistry?

Properties of Canal rays They are the streams of positive ions of the gas enclosed in the discharge tube. The mass of each ion is nearly equal to the mass of the atom. ii. They are deflected by electric and magnetic fields.

What are two properties of cathode ray?

Property 1: Cathode rays travel in a straight line and can cast sharp shadows. Property 2: Cathode rays are negatively charged. Property 3: Electric field and magnetic field deflect cathode rays.

What is properties of cathode and anode rays?

Cathode rays contain material particles (electrons) which are negatively charged. Anode rays contain material particles which are positively charged. These rays are deflected in both magnetic and electric fields. These rays are deflected in both magnetic and electric fields.

What are cathode rays give three features of it?

The characteristics of cathode rays are:

• They consist of negatively charged particles.
• Cathode rays are also called as electrons.
• Electrons are lighter than the Hydrogen atom.
• Electrons mass is very small or less.

Who discovered cathode rays class 11?

Electrons were discovered as the constituents of cathode rays in 1897 by British physicist J. J.Thomson. He showed the rays were composed of a previously unknown negatively charged particle, which was later called the electron.

What are canal rays class 11?

These are positively charged radiations that consist of particles having charges equal in magnitude. Canal rays can also be described as the beam of positive ions obtained by gas-discharge tubes. The mass of canal particles is extremely more than that of electrons, it is about times larger.

What are cathode rays short answer?

Cathode rays are a beam of negatively charged electrons traveling from the negative end of an electrode to the positive end within a vacuum, across a potential difference between the electrodes.

What was the result of the cathode ray experiment Class 11?

The charge and mass of cathode rays does not depend on the nature of gas in the tube. Cathode rays contain negatively charged particles called electrons. As all the gases produce cathode rays, it was concluded that all the atoms contain electrons.

How are anode rays produced Class 11?

The Anode rays are produced as a result of the bombardment of high-speed electrons from cathode rays on gaseous atoms, which knocks electrons out of them. Ans : When electrons emitted from the cathode collide with gas atoms in the tube, they strike one or two extra electrons out of these atoms.

What are cathode rays in physics?

cathode ray, stream of electrons leaving the negative electrode (cathode) in a discharge tube containing a gas at low pressure, or electrons emitted by a heated filament in certain electron tubes.

What are the five characteristics of cathode rays?

Solution : The characteristics of cathode rays are:-
(a) They travel in straight lines with high speed.
(b) They exert mechanical pressure.
(c) They produce heating effect when they strike then metal sheets.
(d) They are negatively charged particles.

What are the properties of cathode and anode rays?

Cathode rays contain material particles (electrons) which are negatively charged. Anode rays contain material particles which are positively charged. These rays are deflected in both magnetic and electric fields. These rays are deflected in both magnetic and electric fields.
