Biot-Savart law (J.B. Biot, F. Savart)
A law defines the contributions to a magnetic field through an electric current. This is analogous to Coulomb's law. Mathematically specking, it is dB = (mu0 I)/(4 pi r2) dl cross e where dl refer to the infinitesimal directed length of the electric current causing by the magnetic field, I refer to the current passing through that directed length, r refer to the distance from that directed length, & e refer to the unit vector directed from the test point to current-generating length.
Fresnel''s diffraction due to a straight edge?
1)The armature ABCD consists of a copper wire wound on cylindrical soft-iron core.The armature can be rotated horizontal axis perpendicular to magnetic field. 2)NS is permanent

give full detail of nicols prism about 20 to 30 pages
What is the difference between diffraction and interference? Diffraction is the bending of waves around an obstacle, whereas interference is the meeting of two waves. For exam
Wave motion is the motion in which the particle/matter remains at the point where it is. But the disturbance/energy gets transfer from one point to the other. The particle just o
