10- In a pipe open at both ends, the natural frequencies of oscillation form a harmonic series that includes all ………………………… multiples of the fundamental frequency.
Explanation / Answer
6- When a wave or pulse travels from medium A to medium B and VA> VB(that is, when B is denser than A), it is NOT INVERTED upon reflection
7- The rate of energy transfer in anysinusoidal wave is proportional to the square of ANGULAR FREQUENCY and AMPLITUDE.
8. A sound wave may be described equally well in terms of either pressure or displacement, where the pressure wave is 90o OUT OF PHASE with the displacement wave in terms of phase.
9. The change in frequency heard by an observer whenever there is relative motion between a source of sound waves and the observer is called DOPPLER EFFECT.
10. In a pipe open at both ends, the natural frequencies of oscillation form a harmonic series that includes all INTEGRAL multiples of the fundamental frequency.
