Question

Why cathode rays cast shadow of any object placed in their path

Answer 1

$\underline{\textbf{Cathode Rays}}$

$\text{A cathode ray Is originate from Negative}\\ \text{charged plate called Cathode.when provided High electricity}$

$\text{ .When Electricity is provided to Cathode in cathode ray tube .}$

$\text{The Particles accerlated in tube to form a spot in vaccum Tube.}$

$\underline{\textbf{Let Know your answer}}$

$\text{A property of Cathode ray tube that it move in Straight Line.}$

$\text{Means if there is a straight Ray}\\ \text{ when strike Object in its way} \\ \text{it's obvious that it will form shadow.}$

$\boxed{\textbf{This states That Cathode ray Travels in Straight line}}$

Answer 2

Answer:

Cathode rays are stream of electrons observed in the discharge tube. Cathode rays travel in a straight line. As it is nothing but the flow of electrons so cathode rays can cast shadow of opaque objects placed in their path.
