Doppler effect (C.J. Doppler)
Waves emitted through a moving object as attained by an observer will be blueshifted (compressed) if approaching, redshifted (elongated) if receding. It takes place both in sound with electromagnetic phenomena, though it takes on different forms in each.
define like and unlike parallel forces
An object is placed 25.0cm from a thin converging lens. A screen is positioned so that a sharp image of the object is seen on the screen. When the object is moved 4.0cm closer to t
Q. A beam of light converges at a point P. Now a lens is placed in the path of the convergent beam 12 cm from P. At what point does the beam converge if the lens is (a)a convex len
Explain the term 'resistivity' and write its S. I . unit. Derive the expression for the resistivity of a conductor in terms of number density of free electrons and relaxation time.
In single sided PCB the conductor tracks run only on one side of copper clad board. Thus crossing of conductors is not permitted. Base material is chosen as per the application. It
