Question

Arrange the following Solid Items in ascending order in respect to Speed of Sound:
(A). Aluminium
(B). Copper
(C). Granite
(D). Steel
Choose the correct answer from the options given below:

• A. (B), (D), (A), (C)
• B. (A), (C), (B), (D)
• C. (A), (C), (D), (B)
• D. (B), (D), (C), (A)

Hint:

Remember, speed of sound increases with greater elasticity and decreases with higher density in solids.

Answer 1

The Correct Option is D

The speed of sound in solids varies based on their density and elasticity:
- Copper (B): Lower speed compared to steel and granite due to its density and structure.
- Steel (D): Higher speed of sound transmission due to its high elasticity.
- Granite (C): Higher speed than aluminium because of its dense and rigid structure.
- Aluminium (A): The highest speed among the given materials due to its low density and high elasticity.
Thus, the ascending order is (B), (D), (C), (A).
