Two notes, R and S, are played in a music room and travel through the same air at the same speed. A microphone connected to an oscilloscope shows four complete oscillations of note R and eight complete oscillations of note S over the same time interval.
Which statement about note S is correct?
It has a shorter period and a shorter wavelength than note R.
It has a longer period and a longer wavelength than note R.
It has a shorter period but the same wavelength as note R.
It has a shorter period but a longer wavelength than note R.
