Answer 1

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.

a shadow of metal cross under the circumstances can be formed only if cathode rays travel in straight lines and cannot be around the corner of the metal cross
