A stretched string fixed at both ends vibrates in n loop. Its length in terms of wavelength is:
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.

A progressive wave of frequency 500 Hz is traveling with a speed of 350 m/s. A compression maximum appears, at a place at a given instant. The minimum time interval after which a rarefaction maximum occurs, at the same place is:
A tuning fork of 512 Hz is used to produce resonance in a resonance tube experiment. The level of water at first resonance is 30.7 cm and at second resonance is 63.2 cm. The error in calculating velocity of sound is:
Consider a stretched string under tension and fixed at both ends. If the tension is doubled and the cross-sectional area halved, then the frequency becomes:
The speed of the waves in the string in terms of the tension F and mass per unit length (m) of the string is given by:
Distance between any two consecutive crests or troughs is called:
Progressive waves of frequency 300 Hz are superimposed to produce a system of stationary waves in which adjacent nodes are 1.5 m apart. What is the speed of progressive waves?
