Cathode rays and their 15 properties

Definition of cathode rays:

Cathode rays are the group of fast moving negatively charged particles. These negatively charged particles are electrons. These rays are shot out at a high speed from the cathode of a discharge tube at a pressure below 0.01 mm of mercury.

15 Properties of Cathode rays:

1.       Cathode rays travel in straight lines.

2.       These rays are deflected by electric field. This is obvious because these rays are nothing but electrons.

3.       These rays travel normally from the surface of cathode. Continue reading “Cathode rays and their 15 properties”

Upcoming science fields to do research and make career

There are many many field in the area of science to do research. One should be completely dedicated towards his or her work for the same, then sky is the limit only.

Let us discuss few of the science fields to do research and make career. The following fields are the broad area, the sub area under each of these fields are so many and will be discussed later on:

1. Environmental Science: We all know that our environment is getting degraded day by day. Thus there are so many research topics and career avenues in this field. The environment science as a subject is taught from schools. Continue reading “Upcoming science fields to do research and make career”
