Ultimate Trivia Quiz On Sound

Let’s start the quiz

Sound is a longitudinal wave, which required a medium to travel. Sound is the vibration which moves parallel to the direction of the wave and the absolute intensity of sound is expressed in watts per meter. The SI unit of sound and loudness is decibels. There is a relative motion between a sound source and a listener, the listener may hear the frequency of the sound differently from its actual frequency, this is called the "Doppler effect". Let's test yourself with a Sound trivia quiz.
