Question

Define

(a) dark current.

(b) transducer.

(c) scattered radiation (in a monochromator).

(d) source flicker noise.

(e) cell positioning uncertainty.

(f) beamsplitter.

Short answer

All definitions are given in their respective step.

Step-by-step solution

Part (a) Step 1. Dark current

Dark current-A little amount of current passes through a semiconductor device when it is not in use, known as dark current. It can be found in all diodes. Leakage current is another name for it.

Part (b) Step 1. Transducer

Transducer-An electrical device that transforms energy from one form to another is known as a transducer. Any device that transforms energy is referred to as a transducer.

Part (c) Step 1. Scattered Radiation

Scattered radiation-A secondary radiation is dispersed radiation. When helpful radiations encounter any thing, these radiations emerge. In a monochromator, scattered radiation is light that reaches the exit slit by reflection and scattering.

Part (d) Step 1. Source Flicker Noise

Source flicker noise-Electronic noise is a sort of source flicker noise. It refers to a signal or process that has a frequency spectrum that is inversely proportional to the frequency. Pink noise is another name for it. It may be found in practically every electrical gadget.

Part (e) Step 1. Cell Positioning uncertainty

Cell positioning uncertainity-The design of the cell holder has an impact on the cell placement uncertainty. It occurs when a cell is not placed in the same location each time.

Part (f) Step 1. Beamsplitter

Beam Splitter-A beam splitter is an optical device that divides a single light beam into two or more beams. Beam splitters come in a variety of shapes and sizes, including cubes, plates, hexagons, and pentagons.
