Question

What are canal rays? Who discovered them? What is charge/mass value of canal rays.

Answer 1

Canal rays:

• Canal rays are the positively charged radiations. They are also called anode rays or positive rays.
• These rays led to the discovery of positively charged particles called protons.
• These rays were discovered by E. Goldstein.
• Charge (e)= 1.6x10^-19 C Mass (m)= 1.67 x10^-24 g
• $\frac{Charge\left(e\right)}{Mass\left(m\right)}=\frac{1.6\times {10}^{-19}C}{1.67\times {10}^{-24}g}=9.58\times {10}^{4}C{g}^{-1}$
