Galvanometer
A galvanometer is an electromechanical instrument for detecting and measuring electric current. The most common use of galvanometers was as analog measuring instruments, called ammeters, used to measure the direct current (flow of electric charge) through an electric circuit. A galvanometer works as an actuator, by producing a rotary deflection (of a pointer), in response to electric current flowing through a coil in a constant magnetic field.
Galvanometers developed from the observation that the needle of a magnetic compass is ....etc

Ground-based radar interferometer for tracking fast approaching targets



Introduction
Many radar systems have been developed in the last 50 years in
various applications including military and industrial
applications . Generally, detection radars and tracking
radars have been installed independently in defence systems
since the two radar systems have different roles within the
military. Detection radars search wide fields of view to find
targets and tracking radars follo ....etc

1. What is data structure?
A data structure is a way of organizing data that considers not only the items stored, but also their
relationship to each other. Advance knowledge about the relationship between data items allows
designing of efficient algorithms for the manipulation of data.

2. List out the areas in which data structures are applied extensively?
1. Compiler Design,
2. Operating System,
3. Database Management System,
4. Statistical analysis package,
5. Numerical Analysis,
6. Graphics,

Abstract:
The Michelson interferometer is a common configuration for optical interferometry and was invented by Albert Abraham Michelson. Using a beam splitter, a light source is divided into two arms. Each of them is reflected back to the beam splitter which then combines its interferometric amplitudes. The resulting interference pattern that is not directed toward the source is typically directed to some type of detector or photoelectric camera. Depending on the particular application of the interferometer, the two paths may be ....etc
