Which of the following statements are correct?
A. The matter wave picture could not incorporate the Heisenberg's uncertainity principle.
B. The wave properties of electrons have been utilised in the design of electron microscope.
C. Electron diffraction experiments have verified and confirmed the wave nature of electrons.
D. Photons are not deflected by magnetic fields.
E. The photon energy is dependent of intensity of radiation.
Choose the correct answer from the options given below:
- A A, B, C and E only
- B A, C, D and E only
- C B, C, D and E only
- D B, C and D only
Answer & Solution
Correct Answer
(D) B, C and D only
Step-by-step Solution
Detailed explanation
The wave nature of electrons is used in electron microscopes (B) and was confirmed by diffraction experiments (C). Additionally, since photons have no charge, they are not deflected by magnetic fields (D). Conversely, A is false because matter waves actually form the basis for…
