Read the following statements carefully and identify the correct statements.
(A) Most interference and diffraction effects exist even for longitudinal waves like sound in air
(B) Optical fibers work on the phenomenon of total internal reflection
(C) Optical density and mass density are the same
(D) Polarisation phenomena are specific to transverse waves like light waves
Choose the correct answer from the options given below:
- A (A) and (D) only
- B (A), (B) and (C) only
- C (A), (B) and (D) only
- D (B), (C) and (D) only
Answer & Solution
Correct Answer
(C) (A), (B) and (D) only
Step-by-step Solution
Detailed explanation
(A) Correct. Both longitudinal and transverse waves exhibit interference and diffraction. (B) Correct. Optical fibers rely on total internal reflection to guide light. (C) Incorrect. Optical density relates to refractive index; mass density is mass per unit volume. They are…
