The fundamental frequency of a resonating pipe is 150 Hz, and the next higher resonant frequencies are 300 Hz and 450 Hz. From this information, what can you conclude

Explanation:

In case of open organ pipe ,

for   fundamental note   2l = wavelength

frequency n = V / Wave length , V is velocity of sound.

f₁ = V / 2I

for   first overtone  note   2l /2  = wavelength

wavelength = l

frequency = V / wavelength

f₂ = V / l

for   second  overtone  note   2l /3  = wavelength

wavelength = 2l /3

frequency = V / wavelength

f₃ =  3V /2l

f₁ : f₂ : f₃ : : 1 : 2 : 3

In case of closed organ pipe ,

for fundamental note   l = 4 x wavelength

frequency n = V / Wave length , V is velocity of sound.

f₁ = V / 4 I

for   first overtone  note   l /  =   3 wavelength / 4

wavelength = 4 l / 3

frequency = V / wavelength

f₂ =3 V /4 l

for   second  overtone  note   l   =  5 wavelength /4

wavelength = 5l /4

frequency = V / wavelength

f₃ =  5 V /4 l

f₁ : f₂ : f₃ : : 1 : 3 : 5.

In case of open organ pipe , frequencies are in any integral ratio.

In case of closed organ pipe , frequencies are only in odd multiple

Since the given ratio are in any integral , the organ pipe must be open organ pipe.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

they should be similar or the same
