The intensity increases by a factor of 4

- 6 dB is incorrect. It will decrease by 12 dB.
The force increases by a factor of 4. If we're talking about gravity, the gravitational force is a function of the masses and the square of the distance between them. As distance decreased by a factor of 2 (since it was cut in half), then the force increases by a factor of 2 squared, and that's 4. Gravitational force increases by a factor of 4 when distance between two gravimetrically attracted objects is decreased by a factor of 2 (cut in half).
The temperature factor increases to 1.1547, approx.
Light intensity
Gravity is the force of attraction between all masses in the universe.The magnitude of a gravitational force depends onthe masses of the objectsthe distance between the objectsThe gravitational force between two bodies increases as their masses increase.
- 6 dB is incorrect. It will decrease by 12 dB.
A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.
The gravitational force then increases by a factor of 4 .
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.
That answer is not easy, but ccroll down to related links and look at "Sound level dependence and the corresponding factors". ten
Decrease by a factor of 9
It's an inverse-square law - for instance, double the distance, and the intensity will be reduced by a factor 1/4.This assumes that there is nothing absorbing the light (for instance, fog); if there is, the intensity in the above example will of course be even less than 1/4 the original intensity.

When doubling the field quantity factor by 2 the level increases by 6 dB. When doubling the energy quantity factor by 2 the level increases by 3 dB. When doubling the sound pressure value by 2 the level increases by 6 dB. When doubling the sound intensity value by 2 the level increases by 3 dB. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity relative to a specified or implied reference level. You usually don't double decibels - you double the factor (ratio). Look at the link "Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power)".
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.
