Q. What is the main difference between diffraction and interference?
A.
Diffraction involves multiple sources, interference does not
B.
Interference involves multiple sources, diffraction does not
C.
Diffraction occurs with sound waves only
D.
Interference occurs with light waves only
Solution
Interference involves the superposition of waves from multiple sources, while diffraction is the spreading of waves when they encounter an obstacle or aperture.
Correct Answer:
B
— Interference involves multiple sources, diffraction does not
Q. What is the main difference between nuclear fission and nuclear fusion?
A.
Fission combines nuclei, fusion splits them
B.
Fission splits nuclei, fusion combines them
C.
Fission occurs in stars, fusion occurs in reactors
D.
Fission is safer than fusion
Solution
Nuclear fission involves the splitting of a heavy nucleus into smaller nuclei, while nuclear fusion involves the combining of light nuclei to form a heavier nucleus.
Correct Answer:
B
— Fission splits nuclei, fusion combines them
Q. What is the main difference between nuclear fusion and nuclear fission?
A.
Fusion combines nuclei, fission splits them
B.
Fusion splits nuclei, fission combines them
C.
Fusion occurs in stars, fission occurs in reactors
D.
Both are the same process
Solution
The main difference is that nuclear fusion combines light nuclei to form a heavier nucleus, while nuclear fission splits a heavy nucleus into lighter nuclei.
Correct Answer:
A
— Fusion combines nuclei, fission splits them
Q. What is the main difference between physisorption and chemisorption?
A.
Temperature dependence
B.
Nature of forces involved
C.
Reversibility
D.
All of the above
Solution
The main difference lies in the nature of forces involved; physisorption is due to weak van der Waals forces, while chemisorption involves strong chemical bonds.
