1.	A person is standing 1 km away from a source of the sound. If the velocity of sound in the medium is 200 m/s, then calculate the number of oscillations (approximately) that the sound wave makes before it reaches that person. The frequency of the sound is 500 Hz.
Answer» A person is standing $1 k m$ away from a source of the sound. If the velocity of sound in the medium is $200 m / s$ , then calculate the number of oscillations (approximately) that the sound wave makes before it reaches that person. The frequency of the sound is $500 H z$ .
