By what factor will the sound of a source change the intensity of the waves if the distance is tripled from the sound source?
For sound intensity (acoustic intensity) we use in the free field (direct field) the inverse square law = 1/r². I1 and r1 belong to the close distance and I2 and r2 belong to the far distance.I2 = I1 * (r1/r2)²I2 = I1 * (1/3)² = I1 / 9Three times farther away gives one ninth the sound intensity of the close sound intensity.
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.
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.
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 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 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.
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.
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 4?
- 6 dB is incorrect. It will decrease by 12 dB.
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)
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.
