A siren emitting at 600 Hz approaches a stationary observer at 30 m/s. If the speed of sound is 330 m/s, the observed frequency is:
View solution →An observer moves directly away from a stationary source at speed $v_o$. The apparent frequency is (sound speed $v$, source frequency $f$):
View solution →A source approaches a stationary observer. The frequency heard by the observer compared to the source frequency is:
View solution →The fundamental frequency of a pipe closed at one end, of length $L$, is:
View solution →The fundamental frequency of an open organ pipe of length $L$ (sound speed $v$) is:
View solution →In a stationary (standing) wave, the distance between two consecutive nodes is:
View solution →For destructive interference, the path difference between the waves should equal:
View solution →For constructive interference, the phase difference between the waves must be:
View solution →The principle of superposition for waves states that the resultant displacement at a point is:
View solution →The speed of sound is generally greater in solids than in liquids or gases.
View solution →The speed of sound in a gas is $v = \sqrt{\gamma P/\rho}$. If the pressure is doubled while keeping density constant, the speed becomes:
View solution →The speed of sound in air at 20°C is approximately:
View solution →A wave has frequency 500 Hz and wavelength 0.66 m. Its speed is approximately:
View solution →Sound waves in air are:
View solution →In a transverse wave, the motion of particles of the medium is:
