How do you know the speed of an electromagnetic wave in a vacuum?

Ivenika [448]

The speed of electromagnetic waves in a vacuum is the same as the speed of light. It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Hope this helps you (:

If an electron is accelerated from rest through a potential difference of 9.9 kV, what is its resulting speed? (e = 1.60 × 10-19

Nata [24]

Answer:

So speed of electron will be $5.89\times 10^{-7}m/sec$

Explanation:

We have given potential difference V = 9.9 KV

Charge on electron $e=1.6\times 10^{-19}$

So energy of electron $E=eV=1.6\times 10^{-19}\times 9.9\times 10^3=15.84\times 10^{-16}J$

This energy of electron will be equal to kinetic energy of electron

So $\frac{1}{2}mv^2=15.84\times 10^{-16}J$

$\frac{1}{2}\times 9.11\times 10^{-31}v^2=15.84\times 10^{-16}$

$v=5.89\times 10^{-7}m/sec$

So speed of electron will be $5.89\times 10^{-7}m/sec$
