4. Your ears detect a sound wave with a frequency of 315 Hz and a sound intensity level of 80 dB. It originated in a vibrating string with a length of 1.9 meters. A) Waves can be longitudinal or transverse. What is the difference between these two kinds of waves? B) This question has one longitudinal wave and one transverse wave. Identify them. C) Recall that the sound you hear from a string is the fundamental frequency, which has a...
1. A bat emits a sound at a frequency of 12 kHz as it approaches a wall. The bat detects beats such that the frequency of the echo is 860 Hz higher than the frequency the bat is emitting. The speed of sound in air is 340 m/s. The speed of the bat is closest to 2. A supersonic plane passes overhead at a speed of 823 m/s. If you hear the sonic boom (shock wave) 4 s after the...
