Question

Do you think that the frequency of echolocation sounds from bottlenose dolphins will be higher or lower than that of the blue whale call described in activity one?

Answer 1

Answer:

The frequency is higher in case of echolocation sounds produced by Bottlenose dolphins. It falls in the range 40,000 Hz to 130,000 Hz, while the calls made by blue whales lies in the range of 30 Hz to 8,000 Hz.

However, the blue whale calls last a lot longer than the echolocation sounds made by the dolphins. A typical blue whale call is between 10 to 30 seconds long, while the dolphin's click is only 50 to 128 microseconds long.

Hope that answers the question, have a great day!
