Why do sounds grow fainter as you get further away from the sound source.?
They spread out, reducing the energy per unit of surface.
When the source of a sound increases its speed increases?
False
How loud is a Boeing 747?
A Boeing 747 at 100 m distance can have a sound pressure level of L = 130 dBSPL.Never forget to tell the distance of the measuring microphone from the sound source, because the closer you are the louder it is.The sound pressure level decreases by 6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
Why intensity decreases as distance from the light source increase?
intensity increases as distance decreases. you cant explain that. scources- bill o'reily
How would you make a bulb in a circuit shine with a fainter light?
If you add resistance to the circuit the bulb will shine with a fainter light ... the higher the resistance is the fainter it will shine
How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX
What is the redshift star?
The redshift is caused by relative motion that increases the distance from the source to the observer. The faster the source of light is moving away to the observer, the greater the redshift

Decibels in ear?
Never forget to tell the distance of the measuring microphone (at the place of your ear), from the the sound source because the closer you are to the sound source the louder it will be.The sound pressure level decreases by 6 decibels per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
When the source of a sound increases its speed increases?
False
How might lower base level affect stream erosion?
increases the vertical distance between the source and destination increasing energy.
How loud is a jet?
A jet at 100 m distance can have a sound pressure level of L = 140 dBSPL.Never forget to tell the distance of the measuring microphone from the sound source, because the closer you are the louder it is.The sound pressure level decreases by 6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
Why does light get dimmer as you move farther away from the light source?
Background ResearchThere are several reasons why light dims with distance. One reason is the shape of the source. For example, if you are holding a flash light, the flashlight's source/bulb is a cone. Therefore, the larger the distance, the more dim it will be. The Light gets more spread out as the distance increases. If you had a piece of chewed gum, and you stretch it out, the thickness of the gum will be small. By doing this, this explains that light gets more spread out as the distance increases. The gum's size becomes bigger, as the gum's width becomes smaller. (WikiAsk)Another reason why light dims with distance is because of the type of light bulb. Let's say you have an ordinary light bulb you bought from Home Depot. And then you buy a LED light bulb that is much more strong and gives much more brightness. Which do you think will be the brightest, regular light bulb, or LED light bulb. The LED light bulb.
Why do echoes get fainter?
Echoes get fainter because each time the sound wave reflects off a surface, it loses some energy due to absorption, scattering, and dispersion. This energy loss causes the echo to decrease in intensity as it repeatedly bounces off surfaces and travels further away from the source.

In radiology what is the term SID?
SID stands for Source to Image Distance. This is the distance between the source of photons (anode) and the image receptor.
