Why do sounds get quieter the further away you are from the source?
Louder or fainter means more intense or less intense of sound vibrations respectively.Intensity in turn is the energy per unit area.Imagine the source of sound to be at the centre of a sphere. When you are far away then the radius of the sphere would be larger and thus the surface area of the sphere also becomes larger.As the energy given out by the source of sound is divided by larger area to get the intensity its value becomes lesser. Hence fainter.Ear drums and microphone diaphragms are moved by sound pressure.Note: Sound power (sound intensity) is the cause - and the sound pressure is the effect. The effect is of particular interest to the sound engineer.Another Perspective:The intensity (loudness) of sound decreases with the square of the distance from the source.
What is inverse square law and an example?
inverse square law is the law that states the intensity of the light, sound etc is directly proportional to 1/ distance squared meaning the further you are from the source the less intense the light etc will be. e.g. an object 1m away from a light source 1/1^2=1 , 2m 1/2^2= 1/4 and so forth
How many meters is the thames?
If you mean the length from its source - it's 346 km (215 miles) long
To what is the illumination of a surface by a light source directly proportional?
The illumination on the surface would be reduced by a factor of four, thereforeif the distance from a light source is doubled, the illumination provided by the source is one fourth as great.
How long is a shadow cast by a person 1.9 meters tall?
It depends on where the light source is. If you're talking about the sun, it depends on what time of day it is.
How does distance affect intensity?
Distance affects intensity by following the inverse square law, which states that as distance from a source increases, the intensity of the source decreases by the square of the distance. This means that the further you are from a source of intensity, the weaker the intensity will be.
What happens to the light intensity if you half the distance to the source?
The light intensity increases by a factor of four when you half the distance to the source. This is known as the inverse square law, where light intensity is inversely proportional to the square of the distance from the source.
What is the relationship between the distance from a source of electromagnetic waves and the electromagnetic wave intensity at that distance?
The relationship between the distance from a source of electromagnetic waves and the electromagnetic wave intensity at that distance is inversely proportional. This means that as the distance from the source increases, the intensity of the electromagnetic waves decreases.
How is the intensity of light and distance related?
The intensity of light decreases as distance from the source increases. This relationship follows an inverse square law, meaning that if you double the distance from the source of light, the intensity decreases by a factor of four.
What is the relationship between the intensity of radiation and the distance from the source, as described by the k square law?
The relationship between the intensity of radiation and the distance from the source, as described by the inverse square law, states that the intensity of radiation decreases as the distance from the source increases. This means that the further away you are from the source of radiation, the lower the intensity of radiation you will be exposed to.
What is the equation that relates the intensity of light to the power of the light source and the distance from the source?
The equation that relates the intensity of light to the power of the light source and the distance from the source is known as the inverse square law. It is expressed as: Intensity Power / (4 distance2)
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 3?
The intensity of a sound wave would increase by a factor of 9 (3^2) if the distance from the source is reduced by a factor of 3. This is because intensity is inversely proportional to the square of the distance from the source.
If the distance from the light source is tripled how much does the light intensity change?
The light intensity decreases by a factor of nine when the distance from the light source is tripled. This relationship is governed by the inverse square law, which states that the intensity of light is inversely proportional to the square of the distance from the source.
What is the relationship between the intensity of the radiation given off from a radiation source and distance from the radiation source?
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
What is the relationship between sound intensity and distance?
The relationship between sound intensity and distance is that sound intensity decreases as distance from the sound source increases. This is because sound waves spread out as they travel, causing the intensity of the sound to decrease with distance.
Why does intensity decreases as the distance from the light source increases?
Intensity decreases as the distance from a light source increases due to the spreading out of light waves over a larger area. This leads to light being more dispersed and less concentrated at a greater distance from the source. The inverse square law dictates that the intensity of light decreases proportionally to the square of the distance from the source.
What happens to the light intensity if you tripled the distance to the source?
For example, assume you are shining a flashlight at the wall. If you move twice as far from the wall, the spot of light will be twice the diameter. If the diameter doubles, then the area of the spot is 4 times as big. Thus, the same light is lighting 4 times as much wall. Thus, the intensity is 1/4 of the original intensity. The intensity varies with the inverse of the square of the distance.
