The distance at any time because of any value of pulse meeting concurrently at a position in a medium is the vector addition of the individual distances due every one of the ray at that point at the same time.
When two waves of similar amplitude on a string approach each other, then on collision, they superimpose to give a resultant pulse of zero amplitude. After crossing, the two waves travel separately as given in as if nothing had happened.
Some Important applications of superposition rule :
(a) Interference of waves
(b) Stationary waves
(c) Beats
when a body is thrown upwards, its velocity becomes zero at the highest point. what will be its acceleration at this point?
Copper losses: These losses occur because of ohmic resistance of the transformer windings. If I1 and I2 are primary and secondary currents correspondingly and R1and R2 are the res
In an adiabatic process, the body neither absorbs heat nor does it refuse energy, i.e. in this phenomena there is no heat exchange (Δ Q = 0). Thus from first law of thermodynam
When a moving body changes with time,then we say that the body has acceleration.simentaniously the change in velocity is equal then it is called uniform acceleration .
an object has moved through a distance.can it have zero displacement?if yes support your answer with an example
A multimode, step-profile fibre has a core radius of 50 microns, a core index of 1.52 and a cladding index of 1.50. (a) If the fibre end-face is excited by a source with a wave

The focal length of a concave mirror is 2 meters. An object is positioned 8 meters in front of the mirror. Where is the image of this object formed? Ans: The image of given ob
FARADAYS LAW: When the magnetic flux through the coil is made to vary, an emf is induced in the coil. The magnitude of the induced emf is proportional to the rate of change of
As electric field is conservation, work done and as potential difference among two points is path independent and depends only on the position of points between which the charge is
