What is the range of frequencies associated with (a) infrasound (b) audible sound, and (c) ultrasound?

Academic Physics NCERT Class 9

(a). Infrasound: The frequency range for infrasound is $0\ Hz-20\ Hz$.

(b). Audible sound: The frequency range for audible sound is $20\ Hz-20,000\ Hz$.

(c). Ultrasound: The frequency range for ultrasound is above $20,000\ Hz$.
