Which wave will diffract the most when passing through a gap that is 1.20 m wide?
wave speed =330 m s−1= 330\text{ m s}^{-1}=330 m s−1, wave frequency =300 Hz= 300\text{ Hz}=300 Hz
wave speed =330 m s−1= 330\text{ m s}^{-1}=330 m s−1, wave frequency =250 Hz= 250\text{ Hz}=250 Hz
wave speed =300 m s−1= 300\text{ m s}^{-1}=300 m s−1, wave frequency =300 Hz= 300\text{ Hz}=300 Hz
wave speed =300 m s−1= 300\text{ m s}^{-1}=300 m s−1, wave frequency =250 Hz= 250\text{ Hz}=250 Hz
