(In the US, light intensity is often expressed in the unit of foot-candles. One foot-candle is equivalent to one lumen per square foot).To sum up, light output is expressed in lumens whereas light intensity is measured in terms of lumens per square meter or lux....
What is the intensity of a sound with a measured intensity level of 84 dB? By what factor will an intensity change for a 3.7 dB increase in the sound level? A certain sound level is increased by an additional 20 dB. By how much does its...
What unit is air pressure measured in?Air Pressure:Air pressure is the weight of the air pushing against a particular area. While we may not think much about air having weight, the gravitational force of the Earth still acts on the atoms of the gases in the atmosphere, pulling them toward...
What is subpixel rendering? Subpixel rendering is a technique used to enhance the sharpness and clarity of text or images on displays. It takes advantage of the individual red, green, and blue subpixels that make up each pixel in many modern displays. By manipulating the intensity of these ...
Sensors come in a wide variety, and each type has strengths and weaknesses. This section provides a detailed look atlaser sensorsthat detect based on received light intensity. What Is a Sensor? A Comprehensive Look at Sensors Learn all about the principles, structures, and features of eight se...
MmHg represents the height to which the pressure in the blood vessels can push a column of mercury in a manometer or sphygmomanometer, which are devices used to measure blood pressure. When a blood pressure reading is taken, two pressure levels are measured: systolic (the pressure during a hea...
Microsatellite marker analysis—microsatellite markers are codominant, polymorphic DNA loci containing repeated nucleotide sequences, typically with 2 to 7 nucleotides per repeat unit; the number of nucleotides in the repeated unit is the same for the majority of the repeats within an individua...
It would be difficult to account for the large range of sound levels in human hearing using a linear scale, so the decibel is a logarithmic unit. Some people describe one decibel as the "just noticeable difference" of intensity between two sounds, but this only holds for quieter sounds. The...
A CMOS sensor contains an array of minuscule cells (photodiodes) that capture photons at their various wavelengths and intensity when the light strikes the chip's surface. A lens is often used to focus the light before it reaches the sensor, as is the case of digital cameras. The CMOS sens...
They measured the station's signal strength Strength Operative effectiveness or potency The strength of the drug. Intensity High level or degree; the property of being intense Strength Intensity, as of sound or light The strength of the wind. Intensity The magnitude of sound (usually in a specif...
