Waves P and Q travel at the same speed. The period of P is three times the period of Q. Which gives the frequency and wavelength of P compared with Q?
Frequency three times as large; wavelength 13\frac{1}{3}31 as large
Frequency 13\frac{1}{3}31 as large; wavelength 13\frac{1}{3}31 as large
Frequency three times as large; wavelength three times as large
Frequency 13\frac{1}{3}31 as large; wavelength three times as large
