Hey mate

If it was helpful MARK AS BRAINLIEST

The streams of positively charged particles are called anode rays or positive rays or canal rays.

In 1886, Goldstein performed a discharge tube experiment, using perforated cathode. He observed that in addition to cathode rays, a new kind of rays were also found. These rays passed through the hole of the perforated cathode but travelled in a direction opposite to that of cathode rays. These rays were found to consist of positively charged particles and were called anode rays or positive rays or canal rays.

These rays are believed to be produced as a result of the knock out of the electrons from the gaseous atoms by the bombardment of high speed electrons of the cathode rays on them. Thus(anode rays are not emitted from the anode but are produced in the space between the anode and the cathode. In other words anode rays (or positive rays) are atomic or molecular residues from which some electrons have been removed. The removed electrons constitute the cathode rays and positive residues form the positive or canal rays.

Properties of anode rays:

(i) Anode rays travel in a straight line.

(ii) These rays are deflected by electric and magnetic fields in a way that shows that these rays are positively charged particles. For example, these rays are attracted towards the negative plate in the electric field which means rays are positively charged particles.

(iii) These rays consist of material particles and rotate the paddle wheel placed in their path.

(iv) Anode rays produce heating effect when struck against a metal foil.

(v) Hie ratio of charge to mass (e/m) for positive rays is considerably smaller than for electrons and is not constant but depends on the nature of the gas taken in the discharge tube. In other words, the value of e/m for a positive ion depends upon the charge of the ion and its mass

HEYthere!

$\huge\mathfrak{♡ANSWER♡}$

↪ ANODE RAYS:

➠Anode rays were identified by Eugen Goldstein.

➠They are positively charged rays which emerge from anode towards cathode in a specially designed discharge tube.

➠These charges rays contain sub atomic particle called protons.

➠They consist of Positively charged particles.

➠These rays are also known as canal rays.

➠Their mass is virtually the same as that of the atoms from which they are derived and is found to be equal to the atomic mass of the gas in the discharge tube.

↪ORIGIN OF ANODE RAYS:

☞When the high voltage is applied to the tube, it ionizes the gas present in the tube.

☞The ions produced collide with atoms of the gas, knocking electrons off of them and creating more positive ions.

☞These ions and electrons in turn strike more atoms, creating more positive ions which are attracted to the negative cathode.These are the anode rays

PROPERTIES OF ANODE RAYS:

⓵They are capable of producing physical and chemical changes.

⓶They can penetrate thin metal foils.

⓷They can produce ionization in gases.

⓸They are deflected by electrical and magnetic fields
