The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction.3.13: Measuring Intensity. Intensity may be the most important aspect of the FITT principle. Engaging in a “cardio” program that does not stress the CR system to the recommended levels will be ineffective. Engaging in a program that overstresses the system can lead to injury and pose unnecessary risks. Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.

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 .

In general, intensity is a synonym for magnitude, degree or strength. It can therefore be used in conjunction with any color property. Nevertheless, it carries special meaning in certain contexts. The intensity refers to different aspects of radiation. When speaking of light, the intensity can mean the number of photons a light source emits.This defines the minimum intensity required to safely and accurately perform a range of tasks. In some organizations light intensity is only measured reactively, typically after a fall or other accident. A more prudent approach is to perform a lighting survey, documenting light levels throughout the workplace.

What is a Lux meter. A lux meter is also called a light meter, it is a device which is used to measure the brightness. The lux meter measures the brightness specifically with the intensity by which the brightness appears to the human eye. This measurement method is different from the measurement of actual light energy produced …One candela per steradian is termed a lumen, which is the measure of light intensity people are most familiar with. However, what matters most in terms of measuring light intensity is the number of lumens falling on a surface, which is expressed as lux. So one lux is one lumen per square meter, this relating brightness to distance from the source.Four key features of a PA measure should be considered when choosing one for a research study: (1) quality of PA measured (e.g. activity type, intensity, frequency, duration), (2) objectivity of the data, subject burden (e.g. time and/or effort required to complete), (3) cost/burden to administer, and (4) specific limitations, discussed above.Purpose [edit | edit source].
