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
The process of apparent change in frequency (or wavelength) of the light because of relative motion among the source of light and the observer is known as Doppler's effect.
why laser show beat phenomenon while LIGHT do not.
A plane monochromatic wave travelling in a homogeneous medium goes into a denser medium. What are the changes in (i) Frequency (ii) amplitude (iii) speed of propagation & (iv) Phas
