WebA blackbody is an object that absorbs all of the radiation that it receives (that is, it does not reflect any light, nor does it allow any light to pass through it and out the other side). The energy that the blackbody absorbs heats it up, and then it will emit its own radiation. The only parameter that determines how much light the blackbody ...

WebA Pt resistance thermometer is to be used to measure temperature. The relationship between resistance and temperature is to be given by the following equation: If R o = 100 Ω, R 100 = 138.50 Ω, and R 200 = 175.83 Ω, determine: (a) the value of the constants A and B; (b) the fundamental interval. 2.

WebThe negative leak in air at constant temperature in general increases with the pressure. This is shown to be due to ionisation of the air produced by the collisions of the negative ions coming from the wire with air molecules. If the P.D. used is small, no ionisation by collisions occurs, and then the negative leak is independent of the WebFor those who don’t know, negative platinum (according to Digital Extreme’s support website) is described as this.
