A fin whale calls at 30 kHz but at the same intensity of sound as the blue whale in question 4. Which call will travel farther? Why?

How far a sound travels depends on the energy or intensity of the sound. Since the intensity of both Blue whale and fin whale are same, both will travel same distance.

I am not very sure of the answer.
4. A blue whale makes a call at 20 Hz in the Pacific Ocean. What is the wavelength of this sound? Show your work.
Speed of sound in water = 1500 m/s
Frequency = 20Hz
Wavelength = speed/frequency = 1500/20 = 75m
5. A fin whale calls at 30 kHz but at the same intensity of sound as the blue whale in question 4. Which call will travel farther? Why?
Speed of sound in water = 1500 m/s
Frequency = 20Hz
Wavelength = speed/frequency = 1500/20 = 75m

So?
I know that was question 4....
How far a sound wave travels doesn't depend on its wavelength or frequency. It depends on its energy. Intensity depends on Energy. Since intensities are same, energies are same and hence they will travel same distance
ok, thanks
welcome!
