What else can I help you with?
In a transverse wave that travels through a medium the molecules of the medium vibrate in which direction?
The molecules vibrate perpendicular to the direction of propagation or motion.
Explain why sound speeds up when the temperature rises?
Sound speeds up when the temperature rises because the molecules in the medium vibrate faster due to the increase in thermal energy. This results in a higher velocity of sound waves through the medium.
In a transverse wave that travels through a medium how do the molecules of the medium vibrate?
The quaggas of the wave, which are the midpoints, start to spasm out of control.
In general how does changing the temperature of a medium affect the speed of sound through that medium?
As the temperature of the medium increases, so does the speed of sound. As the temperature decreases the speed of sound decreases (this is true for air, at least). To calculate speed of sound in air: V = 331 + 0.59T where T is the air temperature in degrees C.
What causes the molecules in a medium to vibrate and form waves?
The transfer of energy.
Why do waves require a medium?
Sound waves are vibrations through a medium, such as air or water. The energy travels from the vibrating source and vibrates molecules in the medium, which push others sending a wave through the medium. Without a medium, there's nothing to vibrate and sound cannot travel.
Mechanical waves are created when a source of energy causes a medium to?
vibrate or oscillate. This vibration is then transferred through the medium, causing particles in the medium to also vibrate. This transfer of energy produces the mechanical wave.
What medium vibrates when a tambuli is sounded?
Air molecules vibrate when a tambuli is sounded. The sound waves created by the vibrating air molecules travel through the air to our ears, where they are interpreted as sound.
Why can sound energy not travel travel through a vacuum?
Sound requires a medium, such as air, water, or a solid, to travel through. In a vacuum, there is no medium for the sound waves to travel through, so the energy cannot propagate. This is why sound energy cannot travel through a vacuum.
When objects vibrate they create?
When objects vibrate, they create sound waves that travel through a medium such as air, water, or solid materials. The vibration causes the molecules in the medium to compress and expand, transmitting the sound energy to our ears where it is perceived as sound.
Why does the speed of sound change if the temperature of the medium change?
The speed of sound is directly proportional to the temperature of the medium. This is because temperature affects the average speed of the molecules in the medium, which in turn affects how quickly sound waves can travel through it. As temperature increases, the speed of sound also increases due to the higher molecular activity.
What happens to molecules when a sound collides with them?
When a sound wave collides with molecules, it causes them to vibrate and transmit the sound energy through the medium. This vibration is what allows the sound wave to propagate through the material by transferring energy from one molecule to the next.
