Question

Tube A has both ends open while tube B has one end closed, otherwise they are identical. The ratio of fundamental frequency of tube A and B is:

• A. 1:2
• B. 1:4
• C. 2:1
• D. 4:1

Hint:

A tube with both ends open has a higher fundamental frequency than a tube with one end closed.

Answer 1

The Correct Option is A

For tubes with open and closed ends, the fundamental frequency is determined by the length and type of ends. Tube A has two open ends, while tube B has one closed end. The fundamental frequency for tube B is half that of tube A.
Final Answer: \[ \boxed{1:2} \]
