During a test, sound level was measured as 90 dB in the operator’s cabin on a tractor. Taking reference sound pressure as 2 * 10-5 N m-2, the measured RMS sound pressure in N m-2 is
A source emits sound of frequency 600 Hz inside water. The frequency heard in air will be equal to (velocity of sound in water = 1500 m/s, velocity of sound in\nair = 300 m/s)
Sound produced at a point is heard by a person after 5 second, while the same sound is heard by another person after 6 seconds. If the speed of sound is 300 m/s, what could be the maximum and minimum
Like sound, light travels as a
