Explanation:
It is given that,
Voltage,
De broglie wavelength in terms of voltage is given by :
m and e are the mass and charge on electron. So,
So, the De broglie wavelength of an electron is 1.53 meters. Hence, this is the required solution.

Answer:
There are a number of models as explained below.
Explanation:
- Depending on the position of the earth in the orbit, stars will be in different positions relative to the distant stars.
