Question
Choose the correct option?
Choices
Choice (4) | Response | |
---|---|---|
a. | Shapes of orbitals are functional representation of mathematical solutions of Schrodinger equations. They do not represent any picture of electric charge or matter. |
|
b. | Smaller the wavelength of the electron wave more is the resolving power of the electron microscope. |
