intensity
(noun)
The degree of depth, strength, or brilliance of a color or light.
Examples of intensity in the following topics:
-
Intensity
- The SI unit for intensity is watts per meter squared or,$\frac W{m^2}$.
- Sound intensity can be found from the following equation:$I=\frac{{{\Delta}p}^2}{2\rho{v_w}}$Δp - change in pressure, or amplitudeρ - density of the material the sound is traveling throughvw - speed of observed sound.Now we have a way to calculate the sound intensity, so lets talk about observed intensity.
- The pressure variation, amplitude, is proportional to the intensity, So it is safe to say that the larger your sound wave oscillation, the more intense your sound will be.
- For a reference point on intensity levels, below are a list of a few different intensities:
- Graphs of the gauge pressures in two sound waves of different intensities.
-
Intensity
- where I is the intensity.
- It turns out that these two quantities both decrease as R−2, so the intensity or brightness is conserved along a ray.
- This result makes the intensity a terrifically useful quantity.
- On the right intensity is the power delivered to an area from a particular part of the sky (solid angle).
- Here the two intensities are equal but the upper set of rays delivers less flux.

Physical and Chemical Properties of Matter
- Properties of matter can be classified as either extensive or intensive and as either physical or chemical.
- All properties of matter are either extensive or intensive and either physical or chemical.
- Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance's chemical identity.
- Recognize the difference between physical and chemical, and intensive and extensive, properties
-
Blackbody Radiation
- The brightness temperature is determined by equating the brightness or intensity of an astrophysical source to the intensity of a blackbody and solving for the temperature of the corresponding blackbody.
- This expression is most useful in the regime where the intensity of the blackbody is proportional to the temperature i.e. the Rayleigh-Jeans limit.
- In what regime does the linear relationship between the brightness temperature and the intensity begin to fail?
-
Thermodynamics
- The brightness temperature is determined by equating the brightness or intensity of an astrophysical source to the intensity of a blackbody and solving for the temperature of the corresponding blackbody.
- This expression is most useful in the regime where the intensity of the blackbody is proportional to the temperature i.e. the Rayleigh-Jeans limit.Here we have,
- In what regime does the linear relationship between the brightness temperature and the intensity begin to fail?
-
Blackbody Temperatures
- The brightness temperature is determined by equating the brightness or intensity of an astrophysical source to the intensity of a blackbody and solving for the temperature of the corresponding blackbody.
- This expression is most useful in the regime where the intensity of the blackbody is proportional to the temperature i.e. the Rayleigh-Jeans limit.
- In what regime does the linear relationship between the brightness temperature and the intensity begin to fail?
-
Polarization
- It is possible to recover this polarization information through intensity measurements.
- Generally one inserts a filter which collapses the incoming wave onto one of the polarization states and one measures the resulting intensity.
- For example, the intensity measured through a polarizing filter aligned along the $1-$direction is $|\epsilon_1 \cdot {\bf E}|^2$.
- One typically makes a series of intensity measurements through filters and quarter wave plates with different orientations and combines the resulting intensities to form the Stokes parameters, $I,Q,U$ and $V$ or $s_0,s_1,s_2$ and $s_3$.
- The first parameter measures the total intensity of the wave, the sum of the intensities of the two linearly polarized measurements.
-
Distribution Intensity
- Product distribution intensity refers to the scale of the distribution network as well as the appropriate selection of location.
- Product distribution intensity refers to the scale of the distribution network as well as the appropriate selection of location.
- In intensive distribution, a producer's products are stocked in the majority of outlets.
- The choice of distribution intensity is extremely critical, because it is an important part of the firm's overall marketing strategy.
- Snack food is a good example of a product that is intensively distributed.

Relationships between ROA, ROE, and Growth
- Return on assets gives us an indication of the capital intensity of the company.
- The formula for capital intensity is below:
- The use of tools and machinery makes labor more effective, so rising capital intensity pushes up the productivity of labor.
- Capital intensity can be stated quantitatively as the ratio of the total money value of capital equipment to the total potential output.
- In other words, changes in the retention or dividend payout ratios can lead to changes in measured capital intensity.
-
Energy, Intensity, Frequency, and Amplitude
- The energy in a wave is proportional to its amplitude squared and the intensity of a wave is defined as power per unit area.
- Therefore, power is more appropriate than energy to describe the "intensity" of a wave.
- All these pertinent factors are included in the definition of intensity I as power (P) per unit area:
- Although you can increase the number of photons by increasing the intensity of a beam, the energy of individual photons in the beam is determined by the frequency of the beam.
