How is communication possible without a physical medium? An unguided transmission transmits the electromagnetic waves without using any physical medium. Therefore it is also known as wireless transmission. In unguided media, air is the media through which the electromagnetic energy can flow easily. What is the role of transmission medium in a network? Transmission media […]

How do you find the specific resistance?
How do you find the specific resistance? Specific Resistance (”ρ”) is a property of any conductive material, a figure used to determine the end-to-end resistance of a conductor given length and area in this formula: R = ρl/A. Specific resistance for materials are given in units of Ω-cmil/ft or Ω-meters (metric). What are the two […]
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 are three common types of optical instruments?
What are three common types of optical instruments? There are three main types of optical telescopes: refractive, reflective, and catadioptric. How are concave mirrors used in everyday life? Concave mirrors are used in reflecting telescopes. They are also used to provide a magnified image of the face for applying make-up or shaving. Concave mirrors are […]
