    Frequency Travel
AI Thread Summary
Lower frequency sounds travel more easily through walls and other materials due to their longer wavelengths, which are inversely related to frequency. The intensity of sound is not directly tied to wavelength; rather, it is influenced by the mass of the materials that reflect or absorb the sound. Heavier materials are more effective at attenuating higher frequency sounds, while lower frequencies can penetrate more easily. The discussion highlights the importance of understanding the relationship between frequency, wavelength, and material properties in sound transmission. Overall, the ability of lower frequencies to travel through barriers is primarily linked to the physical characteristics of the sound and the materials involved.

1. Apartment dwellers will testify that bass notes are more distinctly heard from music played in nearby apartments. Why do you suppose lower-frequency sounds travel through walls, floors, and ceilings more easily?



2. n/a



3. Lower frequency sounds travel through walls, floors, and ceilings more easily due to the fact that lower frequency sounds have higher wavelengths which increase the intensity of the sound which is heard through the various mediums.

I want to make sure if my answer is correct or am I confusing something? Thanks in advance for your help!

No, your answer is wrong on both counts. First: what is the relation between frequency and wavelength? Second, why do you think wavelength is coupled to intensity?
 


Lower frequency = higher wavelength and higher frequency = lower wavelength; frequency and wavelength are inversely proportional

I thought that that wavelength and intensity are related to each other...since lower frequency = higher wavelength which I thought meant greater intensity?
 


Sorry, I didn't realize that you are using "higher" to mean longer. Yes, higher frequencies have longer wavelengths. However, wavelength and intensity are unrelated.

The answer to the question has more to due with the mass of material needed to reflect or attenuate the sound. It works for sound production too--consider the size and weight of a woofer (producing bass) compared to that of a tweeter (high notes) to get your thinking started in the right direction.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
