1. In interference all fringes are of same width while in diffraction fringes are not of same width. 2. In iterference all bright fringes are of nearly same intensity. In diffraction intensity goes on decreasing with order of maxima. 3. Interference is the result of intensity between light waves from source of light. Diffraction is the result of diffraction between secondary wavelets from parts of same wave front.

Why is frequency of outgoing and incoming signals different in a mobile phone

Yogita Ingle 7 years ago

Incoming and outgoing signals from the handset have different frequencies to avoid interference between units in adjacent or closely spaced cells. The same frequencies may be reused in cells that are sufficiently geographically separated from each other to prevent interference there between.

ANSWER

For a single slit of width "a" the first minimum of the interference pattern of a monochromatic light of wavelength lambda occurs at an angle of lambda/a we get a maximum for two narrow slit seprated by a distance a explain.

Sayeda Iram Ateeq 7 years ago

If the refractive index of the medium (in which the lens is placed) is greater than the refractive index of the lens, then the property of the lens get reverse. i.e, the convex lens act as concave lens.

What is Cauchy formula?

Silent Punk 7 years ago

In mathematics, Cauchy's integral formula, named after Augustin-Louis Cauchy, is a central statement in complex analysis. It expresses the fact that a holomorphic function defined on a disk is completely determined by its values on the boundary of the disk, and it provides integral formulas for all derivatives of a holomorphic function. Cauchy's formula shows that, in complex analysis, "differentiation is equivalent to integration": complex differentiation, like integration, behaves well under uniform limits – a result denied in real analysis.

Yogita Ingle 7 years ago

Resistivity is also known as specific resistance.
It is the resistance of the specific material; also it is specific to a material.
R=ρ, If A and L =1 in Equation R= ρ (L/A).
Resistivity is defined as resistance of unit length and unit area of a conductor.
