Wave Application Quick Check

1.) A wave travels at 1,500 m/s with a frequency of 5 hertz. What is its wavelength?
-300m-

2.) Humans can hear thunder at different frequencies. These correspond to wavelengths ranging from 2.75 to 16.5 meters. If the speed of sound is approximately 330 m/s, what frequencies of thunder can humans hear?
-20 to 120 hertz-

3.) Two similar waves X and Y travel through the same medium. Wave X has a frequency of 200 hertz and a wavelength of 35 meters. Wave Y has a frequency of 700 hertz. What is the wavelength for wave Y?
-10 meters-

4.) While traveling in the same medium, sound A has a wavelength of 5 meters, while sound B has a wavelength of 10 meters. Which sound will have a higher pitch?
-sound A, because it has a higher frequency-

5.) California sea lions communicate underwater at frequencies ranging from 500 to 4,000 hertz. The speed of sound in sea water is approximately 1,500 m/s. What are the approximate wavelengths of sound with which the California sea lions communicate?
-0.375 to 3 meters-

yes, all the same though. distance = speed * time
time = 1/ frequency

weakinsomniac Is right I got a 5/5

Weakinsomniac is 100% correct!!!!

Still correct

weakinsomiac is 100% correct, thanks !

He's totally correct

still correct in april

weakinsomniac is clutch 1000 broh

!!YALL CRAZY :)!!

The approximate hearing range of humans is 20 hertz to 20,000 hertz, and that of dogs is 67 hertz to 45,000 hertz
Who will hear a wave traveling through air at 300 meters/second if the distance between two adjacent wave crests is 0.01
meter?
the correct answer : dogs only

nice to see cum_bucket again

still correct

Cum_bucket and see men should kiss

Weakisominac is correct

LETS GOO THEY"R BACK

Who the hell isn't behind on their work fr

still correct
