Sound Waves

It is unlikely for loud sounds from traffic to break glass objects inside a school unless the glass is already compromised or the sound is extremely loud and very close to the glass. Glass is typically designed to withstand common noise levels found in urban environments.

In a standard non-electronic telephone the transmitter is wired between the two incoming wires of the telephone line. A 'carbon granule' transmitter consists of a small tube filled with carbon granules with a piston at one end attached to a diaphragm. Sound waves cause the diaphragm to vibrate and compacts or loosens the granules altering their electrical resistance in sympathy with the sound. This modulates the line current and is received at the telephone exchange via a transformer called a 'transmission bridge'.

Plastic can help reduce sound waves from passing through, but it doesn't completely stop them. Thicker and denser plastic materials will be more effective at blocking sound. Sound can still travel through gaps or cracks in the plastic, so sealing the edges can improve soundproofing.

You don't necessarily have to go so high to break a glass, rather it is hitting the exact same frequency of vibration that the glass has. So you would tap the glass to determine the frequency (you need someone with perfect pitch or an analyzer), and then you just have to hit that same note at the right intensity to break the glass.

Sound waves are not made up of chains and vibrating chains. They are actually longitudinal waves that travel through a medium, such as air or water, caused by the disturbance of particles in that medium. These disturbances create a pattern of compressions (high pressure) and rarefactions (low pressure) that propagate as a wave.

The factors that determine an instrument's tone color include the instrument's material and construction, the shape and size of the instrument, the way it is played or struck, and any modifications made to the instrument such as adding dampening materials or mutes. The combination of these factors ultimately gives an instrument its unique sound signature.

I think all EM waves refract AND reflect, however, this would be very hard to

demonstrate in the lab because of the wavelengths (and materials) involved.

============================

Reflection of E&M waves is indeed difficult to demonstrate in the lab, except

when you look at yourself in the lab's mirror.

Refraction is also nearly impossible to demonstrate, unless you wear glasses.

Refraction an reflection can be demonstrated in the lab with water waves, and

with a bit of cleverness and innovation, with sound waves too.

The lowest pitch in the universe is difficult to define precisely, but it is generally considered to be the fundamental frequency of a black hole, known as a "black hole tone." This extremely low frequency would be beyond the range of human hearing.

Sound waves are made up of compressions and rarefactions of particles in a medium, which travel in a longitudinal direction. Longitudinal waves involve the movement of particles parallel to the direction of wave propagation, unlike transverse waves where particles move perpendicular to the wave direction.

By tuning musical instrument we mean that to produce a note of Desired frequency. Take a standard musical instrument of well defined frequency. The new musical instrument and the standard instrument are sounded together. Initially we will hear mixed sound due to slightly frequency difference between them. The frequency of the musical instrument is gradually adjusted till we will hear same sound. When this happens, the musical instrument Will produce the note of desired frequency and is said to be turned. In this way, beats become useful in tuning a musical instrument.

Sound waves can enter the skull through the vibrations of the bones in the skull, especially the temporal bone. These vibrations transmit sound waves to the inner ear, where they are then converted into electrical signals that are interpreted by the brain as sound.

Metals such as aluminum, copper, and steel are known for their ability to conduct sound well due to their high density and stiffness properties. These metals are commonly used in musical instruments like brass instruments, guitar strings, and drum cymbals to produce and transmit sound effectively.

Because the sound played backwards is unnatural to our ears, and since our minds aren't used to the concept of backwards-playing our natural response is to be scared or nervous of it, as with many other things unknown to us. Of course backwards-recordings don't provoke any kind of curses or anything to be scared or worried about.

No, temperature does not depend on sound waves. Sound waves are a form of mechanical energy that propagate through a medium, such as air or water, whereas temperature is a measure of the average kinetic energy of the particles in a substance. These two phenomena are not directly related to each other.

An oscilloscope is used to measure sound waves because it can visually represent the waveforms of sound signals in real-time. This allows for precise measurements of characteristics such as frequency, amplitude, and waveform shape, which are essential in analyzing and troubleshooting audio systems and equipment. Additionally, an oscilloscope can provide a visual representation that helps in identifying distortions or anomalies in the sound wave.

Bats use the sounds they create in an important navigation method called echolocation, which lets them sense objects from the sound reflecting off of those objects. This requires their ears to be adapted to their voice, though their sounds are often unique pulses.

The lub sound occurs around the peak of the R wave in an ECG because it is associated with closure of the mitral and tricuspid valves, which happens at the beginning of ventricular contraction. This coincides with the R wave, which represents ventricular depolarization and the onset of ventricular systole.

Sound waves are mechanical waves that require a medium to propagate, so they can diffract around objects as they interact with the medium. On the other hand, light waves are electromagnetic waves that do not require a medium to travel through, and they tend to move in straight lines unless they encounter a medium or surface that causes them to reflect, refract, or diffract.

Sounds waves as they spread out get weaker and weaker until they just about disappear. Theoretically there will always be some small amount of sound still propagating forever but it will be so weak that it would be unmeasurable. Even if we had the ultimately sensitive listening device and could still detect (hear) sounds from long ago there would be so many other old sounds mixed together that all we would hear would be just noise, probably sounding like a hiss or a humming sound.

In clear unobstructed air sound can be heard very clearly, very far away. When sound encounters glass wool or any other obstruction then sound is slowed down to a great degree or stoped altogether.

The pitch of sound depends on the frequency of the sound wave. Higher frequency waves result in higher pitch sounds, while lower frequency waves result in lower pitch sounds.
