Correct Answer: Audible Wave

Solution : The correct option is the Audible Wave .

The audible range for humans is between 20 Hz and 20,000 Hz. The speed of a wave (v) is related to its wavelength (λ) and frequency (f) by the equation: v=f⋅λ. With a wavelength of 0.3 m and a speed of 300 m/s, the frequency is 1000 Hz, which corresponds to an audible wave.
