Two loudspeakers 5.0 m apart are playing the same frequency. If you stand 11.0 m in front of the plane of the speakers,centered between them, you hear a sound of maximum intensity. Asyou walk parallel to the plane of the speakers, staying 11.0 min front of them, you first hear a minimum of sound intensity whenyou are directly in front of one of the speakers.

If you stay 11.0 m directly in front of one of the speakers, for what other frequencies between 100 Hzand 1000 Hz is there a minimum sound intensity at this point?

Express your answer numerically. If there is more than one answer, enter your answers in ascending order separated by commas.
