Question

cathode rays pass through thin foil of metal but anode rays were not why

Answer 1

Cathode rays are positively charged while anode rays are negatively charged. When anode rays are passed through a foil the positively charged nucleus attracts the rays and thus it doesn't pass however when cathode rays pass through the foil as they are positively charged and same charges repel each other the positively charged nucleus doesn't attract and it is free to pass through the empty space of the atoms. Thus cathode rays pass through thin foil of metal but anode rays doesn't...
