In the sound wave that is traveling from the guitar string to your ears, what is the distance between adjacent condensations? (For the speed of sound in air use the value, at 20 degrees Celsius, from the inside front cover of your textbook.)

52.5cm

Explanation:

First determine the wavelength of sound wave in air . i.e

λ= velocity/frequency

where,

velocity 'v' is 343 m/s

frequency 327 hz

λ= 343/327

λ = 1.049 m => 104.9cm

next is to determine the distance between adjacent condensations  by taking half of the wavelength which we have found above.

= 1/2 x wavelength

= 1/2 x 104.9

= 52.5 cm

therefore, the distance between adjacent condensations is 52.5cm

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
