Sound wave a has lower frequency than sounds wave b but both waves have the same amplitude . What must also be true of these two waves ?

Explanation:

Higher the frequency smaller will be the wavelength. Higher frequency have shorter wavelength and lower frequency waves have larger wavelength. Also, Beats are formed by the superposition of two waves with slightly different frequencies but with similar amplitudes. In time, waves switch between constructive interference and disruptive interference, giving the resultant wave a time-varying amplitude.

Wave A has a lower pitch

Explanation:

I got it right

c most likely

hop this let me know if it is wrong

idk
