write an experiment to show that cathode rays travel in straight line
Answers
Answer:
William Crookes in 1879 demonstrated that cathode rays travel in straight lines. He placed an opaque object like metal cross in the path of cathode rays in a discharge tube. It was observed that a sharp shadow of the cross was cast on the glass behind the cross.
Answer:
Cathode rays travel in straight line can be demonstrated by William Crookes experiment.
Explanation:
Cathode rays are defined as a beam of electrons observed in a high vacuum tube.
William Crookes in 1879 proposed an experiment to demonstrate the traveling in straight line property of cathode rays. In his experiment he used a opaque metal plate and placed it infront of cathode rays in a discharge tube, so that the rays will cross the metal. when cathode rays are allowed to pass it was observed that, a shadow of metal was formed on the glass behind the metal and opposite to cathode rays. Hence, a shadow of the metal thing can be formed only if the cathde rays travel in a straight line.
