How does distance affect intensity of radiation?
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.
How does light intensity vary with distance form the source?
Light intensity is inversely proportional to the square of the distance: I = k/d2
Does sound Intensity decrease linearly with distance?
No, it follows the inverse square law. That is, the intensity is inversely proportional to the square of the distance. I2/I1 = (r1/r2)². Intensity decreases with 1/r² from increased distance, while the sound pressure decreases only with 1/r from increased distance.
What things will affect the light intensity?
Dawn and dusk (twilight), gathering storm clouds, or an overcast sky, all will affect daylight intensity.
What happens to the intensity of ionizing radiation when you move away?
The intensity reduces in proportion to the square of your distance from the source.

Why does moving away from a radio affect the loudness you hear?
because sound waves spread out, intensity decreases with distance from the source.
How does light intensity vary with distance form the source?
Light intensity is inversely proportional to the square of the distance: I = k/d2
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.

What physical law describes the manner in which the intensity of sunlight changes as the observer moves away from the sun?
The Conservation of Energy or power Law. This gives the inverse distance law of Intensity: Intensity on Earth = intensity on sun (radius/sun distance to earth)2 .
Does the intensity of a color affect how you feel?
Yes.
What happens to the intensity of ionizing radiation when you move away?
The intensity reduces in proportion to the square of your distance from the source.
The intensity of a sound describes?
Its loudness at a particular distance
What distance is the sound intensity level 25dB?
That depends on the sound intesity level at the point of origen. Sound fall of with the square of the distance but the original intensity must be known.
How does lever length affect the intensity of an exercise?
Lever length refers to joint flexion or extension. Longer is a higher intensity and shorter is less intensity.
