If the electron has a speed equal to 9.10 x 10^6 m/s, what is its wavelength?

Explanation:

Given that,

The speed of an electron,

We need to find the wavelength of this electron. It can be calculated using De -broglie wavelength concept as :

h is the Planck's constant

So, the wavelength of the electron is . Hence, this is the required solution.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
