Question

The ratio of speed of the electrons in ground state of hydrogen to speed of light in vaccum is

Answer 1

Answer:

Explanation:

The velocity of electron in ground state of hydrogen atom is 2.6 x 10^6 m/s.

Speed of light in vacuum is 2.99 x 10^8 m/s.

Ratio= (2.6 x 10^6)/(2.99 x 10^8)

= 0.869/10^2

= 8.69 x 10^(-3)

Hope it's help.you ...

Have a great day...

Thanks...

Answer 2

Answer:

The velocity of electron in ground state of hydrogen atom is 2.18 x 10^6 m/s.

Speed of light in vacuum is 2.99 x 10^8 m/s.

Ratio= (2.6 x 10^6)/(2.99 x 10^8)

= 0.869/10^2

= 8.69 x 10^(-3)
