This question is not as it seems.I know about the whole jaw thing,But what I am
asking is how the low frequencies Blue whales make are transmitted through very
large areas of water.Since water is thick compared to air I would think they
would need a high frequency. I have bookmarked sites where can listen to whale
calls and the Sperm whales who live where the water is high pressure,seem to
have high frequency calls.Please tell me why Blue whales make and transmit low
sound frequencies through large areas or water.Thank you.
