Explain about the term spatial coherence of Laser.
Spatial coherence:
This coherence is a measure of the correlation among the phases of a light wave at several points’ transverse to the direction of propagation. This coherence tells us how identical the phase of the wave front is. More exactly, the spatial coherence is the cross-correlation in between two points into a wave for all times. When a wave has only one value of amplitude over an infinite length, then this is absolutely spatially coherent.
Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential in the hollow conducting shell is found to be:
Ans) In the first one..... F=ma...the only force which acts is F...which causes an acc. of ''a'' to the body of mass m... and as the force=>F=ma but on the second... let .
.In order to deposit films of the alloy YBa2Cu3, the metals Y, Ba, and Cu are evaporated from three point sources. The latter are situated at the corners of an equilateral triangle
a picture frame is hanging by two verticle strings the tention in the string are 3.8N and 4.4N find the weight of the picture frame
what is wedge constraint? explain with example.
Describe the Michelson Morley's experiment and explain its negative result. What is "Length Contraction" and "Time Dilation" in relativistic mechanics? Explain.
Vectors Representing Forces A force can be represented by a vector (drawn as an arrow). The arrow's length is related to the size of the force and the arrow's direction shows y
