Physics 2: Waves and Sound

A F note has a wavelength of 98.8 cm. Calculate its frequency.

A person is standing on the south side of a canyon and shouts. She hears the echo in 0.44 seconds. Assuming the sound bounced off the other side of the canyon and came back, how wide is the canyon?

What happens to the wavelength and the frequency of a note as you go up one octave?

A tube is open on one end and closed on the other. Draw the largest and second largest standing waves.
