Question

State whether true or false.Anode rays start from anode and ends at cathode.

Answer 2

@iPwnBunnies

Answer 3

true

Answer 4

@Koikkara

Answer 5

u sure @ikatouni ?

Answer 6

@ujjwal

Answer 7

positive

Answer 8

@Abhisar hmm...The anode of a device is the terminal where current flows in from outside. The cathode of a device is the terminal where current flows out. As always, electrons flowing in is the same as positive current flowing out, and vice versa.

I don't know if there is much simple explanation than this ! So is it true ?

Answer 9

No no...i am talking about gas discharge tubes

Answer 10

@Koikkara

Answer 11

lol, just a min...

Answer 12

ok \(\huge\ddot\smile\)

Answer 13

Well...Under the influence of high potential difference, the gas in the discharge tube is ionised. This results in the formation of particles with positive and negative charge. The negatively charged particles ( electrons ) move towards the anode at very high speeds. On the their way they collide with the molecules of the gas producing more electrons and positively charged particles. The electrons move towards anode in the form of cathode rays while positive ions move towards cathode in the form of anode rays or canal rays.

So what u think so ?

Answer 14

Then i think it should be false

Answer 15

because the positive ions are not generated at anode, but are ionised gas particles inside. M i correct ?

Answer 16

possible too ! unfotunately, I think,... On passing the electric discharge at low pressure, Anode rays are deflected by electric field towards negatively charged plate. This deflection indicates that they are positively charged.
Anode rays are deflected by magnetic field. The direction of deflection indicates that they are positively charged. Also, Charge to mass ratio of these particles in the canal rays depends upon the nature of the gas taken in the discharge tube.

Answer 17

so why unfortunately ?

Answer 18

u r ryt about wat u said. Even i was thinkin the same

Answer 19

but i saw some animations on the youtube showing a different story. They depict the anode rays generating at anode

Answer 20

because, Goldstein discovered the existence of a new type of rays in the discharge tubes during (1886) and still no change or improvement in its tube studies ! Still all continue studying old stuffs !

Answer 21

ohkay..so according to u..what should be the answer..true or false..i feel like it should be false !

Answer 22

also there is one evidence which states that no rays are formed if there is complete vacuum inside the tube !

Answer 23

??

Answer 24

Well, the nature of anode rays depends upon the nature of gas taken in the discharge tubes so, if there is complete vacuum inside the tube, ofcourse no rays are formed ..as anode rays are formed due to the ionization of atoms or molecules of the gas taken in the discharge tube .

Answer 25

yes..so u will also say like false i guess ??

Answer 26

exactly... u have the point !

Answer 27

Yay..!!

Answer 28

Thnx @Koikkara !

Answer 29

Welcome, Have a Nice Day !
