Transverse mechanical waves can propagate:
Correct answer: C. in metal but not in gas
- A. both in gas and metal
- B. in gas but not in metal
- C. in metal but not in gas
- D. neither in gas not in metal
Explanation
Transverse and longitudinal waves can be set up in solids. In gases transverse waves die out very quickly and usually cannot be produced at all.

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.
