just thinking it out ones no calculating involved...
1. If you heard a higher pitch from a trumpet than from a saxophone, how do the frequencies of the sound waves from the trumpet compare with those from the saxophone?
2. Why do high frequency waves work better than low frequency waves?
3. As a Dolphin swims toward a fish, it sends out sound waves to determine the direction the fish is moving. If the frequency of the reflected waves is increased, is the Dolphin catching up or falling behind?
for question 2 it should read as follows:
Dolphines can produce sound waves with frequencies raging from 0.25 kHz to 220 kHz, but only those in the upper end of this spectrum are used in echolocation. Explain why do high frequency waves work better than low frequency waves.
