Sound travels in air at a speed of $v = 340$ m/s and has a wavelength of $\lambda = 0.68$ m. Find the period of oscillation.
A sound wave travels at a speed of $v = 340$ m/s. The oscillation frequency is $f = 170$ Hz. Find the wavelength.
Two coherent sources excite waves of wavelength λ = 0.5 m. At some point P the path difference of the waves is Δ = 1.25 m. Is there reinforcement or attenuation of the oscillations at this point?
