Sound travels spherically from where it was made. If energy is to be conserved a sphere of an earlier point will have a higher flux density than one from a later point.
What else can I help you with?
What happens to light as it moves away from its source?
As light moves away from its source, it spreads out and becomes less intense. This is known as light attenuation. The further the light travels, the more it scatters and loses energy, resulting in a decrease in brightness.
When the source of a sound is moving its speed incress?
When the source of a sound is moving, the speed of sound waves emitted from the source is not affected by the motion of the source itself. However, the perceived frequency of the sound may change due to the Doppler effect, if the source is moving towards or away from the listener.
Can thunder always be heard?
well, if your far away then no. you wouldn't be able to hear the thunder. if how ever, you are close to the thunder storm you will hear thunder.
Is it possible to move a source of sound relative to a stationary observer so that there is no shift in the frequency of the sound?
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
Why do you often see a plane before you hear it?
Light travels much faster than sound. Light goes 186,000 miles per second. Sound travels at about 720 miles an hour. The light reaches your eye long before the sound gets there.
What happens to the energy of a sound wave as the source gets farther away?
As a sound wave travels away from the source, its energy spreads out over a larger area, leading to a decrease in the intensity of the sound. This reduction in energy leads to a decrease in the loudness of the sound as it travels farther away.
Why does the loudness of a sound wave decrease as the wave travels away from it source?
The energy in the sound's vibration dies down, until it is no longer audible.
Why does the loudness of a sound wave decrease as the wave travels away from its source?
The loudness of a sound wave decreases as it travels away from its source due to the spreading out of energy in all directions. This phenomenon is known as sound attenuation, where sound energy is dissipated through interactions with the surrounding medium. Additionally, absorption, reflection, and scattering of sound waves by air molecules and obstacles in the environment contribute to the decrease in loudness.
How is the intensity of a sound related to the distance between the source and the receiver?
The intensity of a sound decreases as the distance between the source and the receiver increases. This is due to the spreading out of sound energy over a larger area as it travels further away, resulting in a decrease in the concentration of energy at the receiver.
How do vibrations produce sound?
A sound wave is a transfer of energy as it travels away from a vibrating source.
What is the relationship between sound distance and the perception of volume in a given environment?
The relationship between sound distance and the perception of volume in a given environment is that as sound travels further away from the source, it tends to decrease in volume. This is due to the dispersion of sound waves over distance, resulting in a decrease in intensity and perceived loudness.
An ambulance siren speeds away from you. what happens to the pitch of the sound?
As the ambulance moves away from you, the pitch of the sound will decrease. This is because the sound waves get stretched out due to the Doppler effect, causing the frequency of the sound waves to decrease as the source moves away.
When the source of a sound is moving the sound waves spread out as it travels away from the listener As this happens what does the listener observe?
a lower-pitched sound
How does sound decrease with distance?
Sound decreases with distance due to the spreading out of sound waves as they travel through the air. This causes the intensity of the sound to decrease, resulting in a lower volume the farther away you are from the source of the sound.
How sound travels away from the source?
Sound travels away from the source in waves, propagating through a medium such as air, water, or a solid material by causing particles to vibrate. As the particles vibrate, they transfer energy to neighboring particles, thus transmitting the sound wave outward. The sound wave will continue to travel until it loses energy and eventually dissipates.
What is the loss of a signals strength as it travels away from its source?
The loss of a signal's strength as it travels away from its source is known as attenuation. Attenuation can be caused by factors such as distance, obstacles, interference, and the medium through which the signal is traveling. As a signal travels further from its source, it experiences a decrease in power and may become weaker or distorted.
What sound energy is less when you are farther from the source?
The volume of sound decreases as you move farther away from the source due to the dispersion of sound waves in the environment. This decrease in volume results in less sound energy being received at a greater distance from the source.
