Atuning fork generates sound waves with a frequency of 240 hz. the waves travel in opposite directions along a hallway, are reflected by walls, and return. the hallway is 46.0 m long and the tuning fork is located 14.0 m from one end. what is the phase difference between the reflected waves(in degrees) when they meet at the tuning fork? the speed of sound in air is 343 m/s. [answer 68.2°] pls show steps

The phase difference between the reflected waves when they meet at the tuning fork is 159.29 rad.

Explanation:

Given that,

Frequency of sound wave = 240 Hz

Distance = 46.0 m

Distance of fork = 14 .0 m

We need to calculate the path difference

Using formula of path difference

Put the value into the formula

We need to calculate the wavelength

Using formula of wavelength

Put the value into the formula

We need to calculate the phase difference

Using formula of the phase difference

Put the value into the formula

Hence, The phase difference between the reflected waves when they meet at the tuning fork is 159.29 rad.

god i hope this !

the ima (higher than 1m) will be greater than the ima with the height of 1m.
