A car sounding its horn at 480Hz moves towards a high wall at a speed of 20m/s, the frequency of the reflected sound heard by the man sitting in the car will be nearest to ________570Hz510Hz480Hz540Hz7. All waves except ______ waves must travel through a medium. WaterLightCompressionalSound8. Which of the following is not true about waves?all waves require a material medium for their propagationwaves transfer energy from one place to anotherelectromagnetic waves have the same velocity in the same mediumparticles of a medium vibrate if there is a wave motion in tte medium9.
