Question

Which of the following is/are derived by Hisenberg in his uncertainty principle?

• A. $△p\times △x=\frac{h}{4\pi }$
• B. $△v\times △x=\frac{h}{4\pi m}$
• C. $△E\times △t=\frac{h}{4\pi }$
• D. $△p\times △E=\frac{h}{4\pi }$

Answer 1

The correct option is A $△p\times △x=\frac{h}{4\pi }$

Hisenberg uncertainty principle states that it is impossible to determine simultaneously, the exact position and exact momentum (or velocity) of an electron.

Mathematically, it can be given as:

$\Delta p\times \Delta x=\frac{h}{4\pi }$
