A bat is flying at 7.00 m/s and is emitting cries at a frequency of 82.0 kHz. It is chasing a moth and is detecting the echoes from the moth. Moths fly somewhat erratically. (a) Calculate the frequency detected by the bat when the moth is stationary (b) flying at 1.00 m/s in the same direction as the bat (c) flying at 2.00 m/s toward the bat

A bat sends of a sound wave 100 kHz and the sound waves travel through air at a speed of v = 343 m/s. (a) If the maximum pressure difference is 1.30 Pa, what is a wave function that would model the sound wave, assuming the wave is sinusoidal? (Assume the phase shift is zero.) (b) What are the period and wavelength of the sound wave?
Sound waves are emitted isotropically (that is, with equal intensity in all directions) from a source. The intensity of the waves 3.00 m from the sourceis 2.60x10 -4 W/m 2. Assuming the energy of the waves is conserved, what is the power of the source?
