The string has a length of 0.65 m and vibrates at a frequency of 880 Hz. a. Calculate the velocity of this wave on the string. Show your calculations and include units in your answer.
The wave on the guitar string also creates sound waves in the air. The speed of the sound waves is 340 m/s in air. The pitch
created by the guitar string matches the pitch heard by an observer.
b. Compare the frequency and wavelength of the wave on the guitar string to the frequency and wavelength of the sound waves in

the air.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

where’s the list ? the question is incomplete

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

hope this ! this is not copied! search it up, it's free of plagiarism!
