Sensation and Perception The intensity at which you lose and regain the tone is your absolute threshold for that particular tone. Weber defined the absolute threshold as the intensity at which the stimulus was detected on 50% of trials.A stimulus detected on, say, 20% of trials is by this definition below the absolute threshold for detection, although of course it is sometimes detected nevertheless.he difference threshold is the average of the two differences between the comparison stimuli and the standard. Weber noticed that the difference threshold is a constant proportion of the initial stimulus intensity.

- (5) The name intensity, symbol I, is usually used in discussions involving collimated beams of light, as in applications of the Lambert-Beer law for spectrometric analysis. (6) Spectral quantities may also be defined with respect to frequency v, or wavelength λ; see spectral radiant energy density above. (7) Fluence is used in photochemistry to specify the energy delivered in a given time interval (for instance by a laser pulse). This quantity may also be called radiant exposure.

- We are used to measuring the sounds we hear in loudness. The sound of your friend yelling is loud, while the sound of your own breathing is very soft. Loudness cannot be assigned a specific number, but intensity can. Intensity is measured in decibels. The human ear is more sensitive to high sounds, so they may seem louder than a low noise of the same intensity.

Translations for luminous intensity Luminous intensity. In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.

Intensity (physics) If a point source is radiating energy in all directions (producing a spherical wave), and no energy is absorbed or scattered by the medium, then the intensity decreases in proportion to distance from the object squared. This is an example of the inverse-square law.n the SI system, it has units watts per square metre (W/m 2). It is used most frequently with waves (e.g. sound or light), in which case the average power transfer over one period of the wave is used. Intensity can be applied to other circumstances where energy is transferred.

What is the definition of intensity? What is the definition of intensity in terms of sound? Sound intensity or acoustic intensity (I) is defined as the sound power (Pac) per unit area (A). The usual context is the noise measurement of sound intensity in the air at a …listener's location as a sound energy quantity (measured in W/m²).

Field strength For the curvature form, see Field strength (theoretical physics) . In physics, field strength or intensity means the magnitude of a vector-valued field. For example, electromagnetic field results in both electric field strength and magnetic field strength.n physics, field strength or intensity means the magnitude of a vector-valued field.

- Intensity is the amount of physical power, expressed as a percentage of maximum, the body uses in performing an activity. For example, it defines how hard the body has to work to walk a mile in 20 minutes or to play a game of tag.

- Intensity. 1. The power or magnitude of light, heat, or whatever else you might analyze in physics class. Intensity is inversely proportional to the square of distance from the source. 2 (a) Excessive and mindless enthusiasm for an activity which is often trivial or pointless. This concept was coined by a group of students from radnor high school when they were bored during gym class.

Difference between frequency and intensity? Best Answer: Frequency means no. of cycles per second or in your case no. of photons hitting per second. Intensity means no. of photons hitting per unit area. This implies radiations emitted will depend upon no. of photons hitting per second and not upon no. of photons hitting per unit area.

- Reference has been made in the preceding chapters to the term intensity in relation to. ultrasound, without giving it explicit scientific meaning. In this chapter, the concepts of.intensity and power of ultrasound are discussed in some detail.efinition: The intensity, I, relative to a reference intensity 10, is defined as: Relative intensity (dB) = 10 logw (1/10). The dB values will be positive if the intensity of interest, I, is larger than the reference. intensity, 10, and negative if I is less than 10.
