Why transverse wave does not travel in air?
Transverse waves require a medium with particles that can move perpendicular to the wave propagation. In air, the particles move in random directions due to their thermal motion, making it difficult for transverse waves to propagate effectively. Longitudinal waves, like sound waves, are more common in air because they involve particle vibrations parallel to the wave propagation.
What three kinds of body parts do sound waves travel through before they reach the brain?
Sound waves travel through the outer ear, then the middle ear, before reaching the inner ear where they are converted into electrical signals that travel to the brain through the auditory nerve.
Ultrasound imaging, also known as sonography, is the diagnostic technique that creates images of deep body structures by recording the echoes of pulses of sound waves above the range of human hearing.
What does the timbre of sound depend on?
The timbre of sound depends on the unique combination of overtones produced by an instrument or voice. These overtones give each sound its distinctive tone color, allowing us to differentiate between different musical instruments or voices. The quality and quantity of these overtones contribute to the overall timbre of a sound.
Is it true that the funnel for sound waves in the ear is the outer ear?
No, the funnel for sound waves in the ear is actually the outer ear. The outer ear acts like a funnel, directing sound waves into the ear canal towards the eardrum, which vibrates in response to the sound waves.
Does sound travel better inside or outside?
Sound typically travels better outside due to fewer obstacles and barriers compared to indoor environments. In open spaces, sound waves can propagate further distances without as much interference or absorption. Indoor spaces, on the other hand, can have more surfaces that reflect, absorb, or disrupt sound waves, leading to decreased sound transmission.
How can a microphone and oscilloscope show a sound wave?
The microphone reacts to changes in air pressure and creates corresponding AC electical waveforms.
The oscilloscope takes the AC waveforms and deflects a moving electron beam in a cathode ray tube, thus producing a moving display of the electrical waveform.
How are echoes minimized in cinema halls?
I would guess that there is no SIGNIFICANT amount of echo, because they were designed that way on purpose. The way this can be done is by covering walls and floors with materials that absorb most sound.
Is propagation of sound exothermic or endothermic process?
Propagation of sound is not a chemical reaction, so it is neither exothermic nor endothermic. Sound propagation involves the transfer of mechanical energy through a medium, such as air or water, as vibrations. This process does not involve the release or absorption of heat.
The electrical signals generated by the ears are sent to the brain via the auditory nerve for interpretation. The brain processes and interprets these signals to create the perception of sound.
Which part of sound wave has molecules that are tightly packed together?
The compression or crest of a sound wave has molecules that are tightly packed together, which leads to higher pressure and increased density compared to the rarefaction part of the wave.
How many decibels of sound does a subway train generate?
It generates 95 decibels at 200 feet. See the decibel comparison chart in the related link for further information.
What gathers light through a lens and project an image on film called?
The thing that gathers light through a lens and projects an image on a film is... its really rather simple. Its a camera. How easy was that! So to explain the process, A camera gathers and bends light with a lense, this lense then projects an image onto a light-sensitive film to record a scene. When you take a picture with a camera, a shutter opens to allow light to enter the camera for a specific length of time.
Soundwaves are typically invisible to the human eye as they are a type of mechanical wave that travels through a medium such as air or water. We perceive soundwaves through our sense of hearing when they cause vibrations in our eardrums, which are then processed by our brain as sound. Specialized equipment like oscilloscopes or spectrograms can be used to visualize soundwaves as waveforms or frequency patterns.
Is collecting sound the same as captureing sound waves?
Collecting sound involves gathering audio signals using a microphone or other recording device. Capturing sound waves refers to the process of converting these sound waves into electrical signals that can be stored or processed digitally. In essence, collecting sound involves capturing sound waves as part of the overall process.
How do scientist use sound waves to find oil deposits?
Scientists use sound waves in a process called seismic reflection to create images of underground layers. Sound waves are sent into the ground and bounce back differently depending on the type of material they encounter. By analyzing the patterns of these reflections, scientists can identify potential oil deposits based on the rock structures and formations below the surface.
What does One subject indeed is but the reverberation of the other mean?
This phrase suggests that one topic or issue is dependent on or intimately connected to the other. It implies that there is a cause-and-effect relationship between the two subjects, with one influencing or echoing the other.
How does sound travel in air compared to how it travels with water?
oh i think its because um um i dont know
um, um i know, though! Air is less dense, so sound travels quickly through it. Water is more dense than air, so sound does not penetrate it as well...so um, um i do know :) haha
Is the basilar membrane receive sound waves via air?
No, the basilar membrane does not directly receive sound waves via air. Sound waves enter the ear through the ear canal and cause vibrations in the eardrum, which then transmit these vibrations to the middle ear bones. The movement of these bones leads to the vibrations of the oval window, which in turn causes fluid in the cochlea to create waves that stimulate the basilar membrane.
What living thing s do not communicate using sound wave?
Some living things that do not communicate using sound waves are plants, which primarily communicate through chemical signals released into the air or soil, and some species of insects that use pheromones to communicate with each other over short distances. Additionally, some marine species, like certain types of fish and cephalopods, communicate using visual signals or bioluminescence.
The imaging technique you are referring to is likely ultrasound imaging. Ultrasound uses high-frequency sound waves to create images of organs and structures inside the body. It is commonly used in medical diagnostics for its ability to provide real-time images without exposing the patient to harmful radiation.
What has to happen to sound wave before they can be transmitted by radiowaves?
Sound waves need to be converted into electrical signals before they can be transmitted by radio waves. This is typically done by using a microphone to capture the sound waves and convert them into electrical signals that can then be modulated onto a radio frequency carrier wave for transmission.
Would you hear a change in pitch if you are on a moving train and the train whistle blows?
Yes, you would hear a change in pitch. As the train approaches you, the pitch of the whistle would sound higher because the sound waves are compressed. As the train moves away from you, the pitch would sound lower as the sound waves are stretched out. This is known as the Doppler effect.
Why have you used non-electrolytic liquid in ultrasonic interferometer experiment?
Non-electrolytic liquids are often used in ultrasonic interferometer experiments because they do not conduct electricity, ensuring accurate measurements of sound velocity without interference from electrical conductivity. This allows for precise determination of properties like density and compressibility of the liquid being studied.
