Wave Concepts
A string is tied on both ends and under a tension FT. A standing wave is formed on the string. For each of the following statements select the correct option.
Solution
• When the tension of the string is decreased, the fundamental frequency decreases.
• If the distance between the two fixed ends of the string is increased, the wavelength that corresponds to the fundamental frequency increases.
• When the amplitude of the wave is decreased, the fundamental frequency stays the same.
• If the distance between the two fixed ends of the string is increased, the wave speed stays the same.
• If the distance between the two fixed ends of the string is decreased, the fundamental frequency increases.
