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. 

c.  Uncertainty in measurement is not due to lack of any experimental technique but due to nature of subatomic particle itself. 

d.  All a. , b. and c. are correct
