One student heated a metal wire to produce high speed electrons. When the electrons struck a metal target, waves were produced in a direction perpendicular to the motion of electrons as shown in the diagram below.

iwik · Answer

A high speed electrons can produce longitudinal waves
B electrons moving at high speed produce electromagnetic waves
C the direction of longitudinal waves is perpendicular to motion of electrons
D the direction of electromagnetic waves is always towards the pull of gravity

What do u think the answer is ?

iwik · Answer

A or C

rushwr · Answer

Wrong

rushwr · Answer

The description says the waves were produced in a direction perpendicular to the motion of the electrons that means it is a transverse wave. Example for transverse wave is Electromagnetic waves. So I think the answer should be B

rushwr · Answer

Longitudinal waves are produced in a direction parallel to the motion of the medium. Do you understand now ?
