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.
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.
How can you increase the intensity of a wave?
To increase the intensity of a wave, you can increase the amplitude of the wave, increase the energy of the wave source, or decrease the distance the wave travels from the source. Increasing the number of waves per unit time can also increase the intensity.
By how many times must the distance from a point source be increased to reduce the sound intensity by half?
The distance must be doubled to reduce the sound intensity by half. This follows the inverse square law, which states that sound intensity decreases in proportion to the square of the distance from the source.
What happens to a sound source as it approaches?
As a sound source approaches, the sound waves it produces become more intense and higher in frequency. This causes an increase in volume and pitch as the source gets closer. Additionally, the perception of the sound may also change, becoming more directional and pinpointed as the distance decreases.

An electric field gets stronger as you?
increase the charge or decrease the distance from the source of the field.

Does gravity increase or decrease with greater distance?
Gravity decreases with greater distance. The force of gravity weakens as you move farther away from the source of the gravitational pull, following an inverse square law.
What distance increase is needed to reduce a sound's intensity from an initial 100dB to a final 80dB?
Sound intensity is inversely proportional to the square of the distancefrom the source.-- Increase the distance from the source by 10 times.-- Sound intensity decreases to 1/102 = 1/100 .-- 10 log ( 1/100 ) = -20 dB-- 100 dB - 20 dB = 80 dB
What happens when the population of antelope gradually increases over time?
The preatador population will most likely increase due to an abundant food 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.
What happens to the source of gravity as you leave earth?
If we consider classical physics (Newtonian explanations) the source is unaffected. The strength of the gravitational pull decreases as the second power of the distance.
What happens to the pitch as a sound source moves closer to listener?
As a sound source moves closer to a listener, the pitch of the sound will increase. This effect is known as the Doppler effect, where the perceived frequency of a sound wave increases as the source moves towards the listener.
