1. Place the choice chamber on the bench. 2. Cover sectors with different layers of translucent material. Leave one sector with no cover. 3. Place a bench lamp directly over the choice chamber and turn it on. 4. Put 20 invertebrates into the choice chamber. 5. Start a stopwatch and leave for two minutes. 6. Record the number of invertebrates in each sector.
certain invertebrates are highly sensitive to light. light often means heat and some don't have a high tolerance of heat.
It is a measure of how the intensity of something varies over time or space (or both).
intensive, exclusive and selective
B:Selective distribution
Intensity in distribution can refer to the level of concentration of distribution efforts in a specific area or among a specific group of customers. It can also refer to the amount of resources, such as marketing and sales efforts, allocated to a particular distribution channel or market segment to increase sales and reach target customers more effectively.
when you want to test led distribution intensity curve and IES files, we will be talk this kind of equipment which is goniophotometer. This device is an automatic light distribution intensity 3D curve testing system. It can test many Optical parameters, like total luminous flux, zonal luminous flux etc. According to IESNA-LM-79-08, we will talk the rotating mirror goniophotometer, like LSG-2000 Goniophotometer with Rotating Mirror, this kind of goniophotometer can fully meet demand, it combined all advantages of goniophotometer, the test result have high accuracy.
*intensity, distribution, color and movement
A good hypothesis for making a flashlight could be that increasing the voltage of the battery will result in a brighter light output, or that using a larger LED bulb will increase the intensity of the light produced.
The intensity of sound is objective in nature as it can be measured and quantified using a decibel scale. Intensity is a physical property of sound waves that can be objectively detected and analyzed using appropriate equipment.
The intensity of sound is found by the amount of energy that flows through a unit area in a certain amount of time. It is measured in watts per square meter (W/m^2) and can be calculated using the formula: Intensity = Power / Area.
