(Harikishan)​

Answer 1

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.

Answer 2

Explanation:

In 1897, British physicist J. J. Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to render an image on a screen.
