A circular platform, 5.0 m in radius, has a pair of 600 Hz sirens, mounted on posts at opposite ends of a diameter. The platform rotates with an angular velocity of 0.80 rad/s. A stationary listener is located at a large distance from the platform. The speed of sound is 350 m/sec.
(i) In situation the longest wavelength reaching the listener from the sirens, in cm, is closest to –
