SCIENCE QUESTION

A dolphin produces a sound with a frequency of 120 000Hz. The wavelength is 1.25 cm , What is the speed of sound in water? Is that faster or slower than in air? Why?

PLEASE ANSWER THE ABOVE QUESTION.

slower because the water is thicker than air :?

it's slower i think

its slower because sound waves take longer to travel through water than it does through air....

I can't give any figures without googling since i did physics A-Level a good few years ago!

It's not my homework!

OK MAYBE I lie! :whistling:

id say faster at a guess cos the particles are closer together so have less distance to travel before banging into another one - and faster still through a solid.

....I think... from what i can remember from GCSE science back in 1994!! - Basically i dont know!

Ok i'd say slower....or faster.

Ok so now I really need to know what the speed of the damn thing is in water! Please

faster in water (denser)

speed = f x wavelength
speed = 120000 x 0.0125
speed = 1500m/s
faster
travels by compressions and rarefactions of the denser medium

from what i can remember it is about 5 times faster

chesso
speed = f x wavelength
speed = 120000 x 0.0125
speed = 1500m/s
faster
travels by compressions and rarefactions of the denser medium


lol o dear! i was good at physics when i studied it :lol:

Thats what i said - well sort of!

Definitely faster!!!!!

Because the particles are closer together, the distance to the next closest particle is therefore shorter which means less distance needs to be traveled to transfer the energy from one particle to another, basically what chesso: said.

WTF did you people learn at school?
