Vibrating at a frequency n. consider the following statements.

• A. The speed of the wave is $4n\times ab$
• B. The medium at a will be in the a same phase as d after$\frac{4}{3n}s$
• C. The phase difference between b and e is $\frac{3\pi }{2}$
• D. The speed of the waves is$2n\times ab$

Answer 1

The correct option is A The speed of the wave is $4n\times ab$
