Fresnel's assumed that a wavefront started from a source can be divided in to a large no. of strips or zone called the Fresnel's zone of small area.
if the path difference between secondary wavelets reaching a point on screen started from two consecutive zone is N2(or the phase difference is 2nd) then the zones are called Fresnel's half period zone..

Is Michigan the same time zone as Kentucky?
Half of Kentucky is located in the Central Time Zone while the other half is located in the Eastern Time Zone, which is the same time zone Michigan is in

Is Newfoundland the only place with a half hour time zone?
Yes. No, it is not. Some places (ie: Nepal) have a 15 minute time difference. . Kabul, Afghanistan is in a half hour time zone and there are others in Australia and in India.
Is it true that The length of time required for half of the radioactive atoms in a sample to decay is its period?
No, the length of time required for half of the radioactive atoms in a sample to decay is its half-life, not period. The half-life is the amount of time it takes for half of the radioactive atoms in a sample to undergo radioactive decay. Period typically refers to the time it takes for a complete cycle of a repeating event.
Is a period of an element the amount of time it takes for half of a radioactive isotope to decay?
Yes, the period of an element is the time it takes for half of a radioactive isotope to decay, also known as the half-life. During this time, half of the radioactive atoms in a sample will undergo radioactive decay, transforming into different elements or isotopes.

Half period zone in a plane wave front?
The half period zone is provided by an optical device known as Zone plate,The zone plate is so called because it is constructed following Fresnel zone law.It is simply a plane parallel glass plate having concentric circles of radii accurately proportional to the square roots of the consecutive natural numbers 1,2,3......etc. The even or odd order annular space between the circles are completely dark.

What is fresnel zone in telecom?
Frensel Zone: Pronounced "fraynel zone." The pattern of electromagnetic radiation that is created by a transmitting station from its antenna to receiving antennas. It is in the shape of an ellipsoid, or 3D ellipse, which looks like an elongated football.
What do fresnel lights do?
The fresnel lights have fresnel lenses that allow for the light to be softer. The fresnel lights also cast a very soft shadow and capture more of an oblique lighting.
