QNEET-2024-Ph-174: NEET 2024 Physics - Class 12 NEET-2024-Ph-174 Solution: Select the correct statements among the following: A. Slow…
Select the correct statements among the following: A. Slow neutrons can cause fission in than fast neutrons. B. -rays are Helium nuclei. C. -rays are fast moving electrons or positrons. D. -rays are electromagnetic radiations of wavelengths larger than X-rays. Choose the most appropriate answer from the options given below
Multiple Choice Options
- A A, B and C only
- B A, B and D only
- C A and B only
- D C and D only
Step-by-Step Verified Solution
(A) Slow neutron can cause fission in 92 235 U than fast neutrons because fast neutrons are too quick so they scatter of atoms instead of being captured by them
(B) _ -rays are Helium nuclei, is a true statement
(C) _ -rays are generated when neutron is converted into proton by releasing electron or proton is converted into neutron by releasing positron.
(D) _ -rays have higher energies as compared to X-rays. So they have smaller wavelength as compared to X-rays.
