A wave have the speed 0.50 m/s. If its wavelength is 1.5 m. What is the period of the wave?
Correct answer: B. 3s
- A. 0.33s
- B. 3s
- C. 1.5s
- D. 6s
Explanation
Correct Option: BAs from the formula we know that Speed-wavelength /Time period....Rearranging the equationTime period =wavelength/speed...As speed =0.50m/s and wavelength is 1.5mPutting in equation 2Time period = 1.5m/0.50m/sTime period =3s

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.
