What are 3 characteristics of microwaves? Following are the main properties of Microwaves. Microwaves are the waves that radiate electromagnetic energy with shorter wavelength. Microwaves are not reflected by Ionosphere. Microwaves travel in a straight line and are reflected by the conducting surfaces. Microwaves are easily attenuated within shorter distances. Why Microwaves are used in […]

What is a good U-value?
What is a good U-value? The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m2k. Roof – 0.15 W/m2k. What is a good window U-value? In a cold […]
What is the basic principle of scintillation detectors?
What is the basic principle of scintillation detectors? a. The basic principle of pulse height spectroscopy is that the light output of a scintillator is proportional to the energy deposited in the scintillation material. The standard way to detect scintillation light is to couple a scintillator to a photomultiplier. What is scintillation efficiency? Scintillation efficiency […]
What is carbon 14 used to date?
What is carbon 14 used to date? Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. What is the lifespan of carbon 14? Carbon-14 has a half-life of 5,730 […]
