A wave is approaching a flat, solid barrier where it undergoes reflection.
Describe how the wavelength, speed, and frequency of the reflected wavefronts compare to those of the incident wavefronts.
The incident wave has a wavelength of 25 cm25\text{ cm}25 cm and a speed of 1.5 m/s1.5\text{ m/s}1.5 m/s. Calculate the frequency of the wave.
Complete the following sentences about sound waves:
