Cathode Rays and Its Properties

Image Credits: Wikipedia, Author: Theresa Knott

Q1: What are Cathode Rays?

Answer: are streams of electrons observed in vacuum tubes. These rays were discoevered by a German physicist Johann Wilhelm Hittorf, and were named in 1876 by E. Goldstein, or cathode rays. In 1897, British physicist J. J. Thomson experimented and showed that cathode rays were composed of negatively charged particles, called electrons. Cathode rays are also called as electrons beam.

When a potential difference of 10 to 15 kV is applied across the two electrodes of a discharge tube and pressure is reduced to 0.01mm of mercury, the rays known as cathode rays are emitted from the cathode. These rays are independent of the nature of the gas in the discharge tube and their direction of propagation is not affected by the position of the anode.


Q2: What are the properties of Cathode Rays?

English Language Reading Comprehension Test - 12 (#cbsenotes)(#eduvictors)

Reading Comprehension 

Set - 12

Read the following passage and answer the questions given below:

There are two problems which cause great worry to our educationists, the problem of religious and moral instruction in a land of many faiths and the problem arising out of a large variety of languages. Taking up the education of children, we see that they should be trained to love one another, to be kind and helpful to all, to be tender to the lower animals and to observe and think right. The task of teaching them how to read and write and to count and calculate is important, but it should not make us lose sight of the primary aim of moulding personality in the right way. For this, it is necessary to call into aid, culture, tradition and religion. But in our country we have, in the same school, to look after boys and girls born in different faiths and belonging to families that live diverse ways of life and follow different forms of worship associated with different denominations of religion. It will not do to tread the easy path of evading the difficulty by attending solely to physical culture and intellectual education. We have to evolve a suitable technique and method for serving the spiritual needs of school children professing different faiths. We would thereby promote an atmosphere of mutual respect, a fuller understanding and helpful co-operation among the different communities in our society. Again we must remain one people and we have therefore to give basic training in our schools to speak and understand more languages than one and to appreciate and respect the different religions prevailing in India. It is not right for us in India to be dissuaded from this by considerations as to overtaking the young mind. What is necessary must be done. And it is not in fact too great a burden.
