Beats only occur when the frequency of two objects is interfere with one another and when those objects are made to identical amplitudes together.
Answer:
approximately 2.99 × 10⁸ m/s
I think it is B. Mechanical waves carry energy through a medium.
Explanation:
A) The distance between the two successive compressions (or rarefactions) is actually called the wavelength of the longitudinal waves.
B) Wavelengths of longitudinal and transverse waves are comparable in the fact that in a transverse wave, the particles move perpendicular to the direction the wave travels whereas in a longitudinal wave the particles are displaced along the direction to the direction the wave travels
