State the principle of superposition of waves.

Statement -1 : The Doppler effect occurs in all wave motions. because Statement-2 : The Doppler effect can be explained by the principal of superposition of waves.

State the principle of superposition ? Why do we use the phrase 'algebraic sum' in the statement ?

Answer the following questions : (a) When a low flying aircraft passes overhead, we sometimes notice a slight shaking of the piture on our TV screen. Suggest a possible expanation. (b) As you have learnt in the text, the principle of linear superposition of wave displacement is basic to understanding intensity distributions in diffractions and interference patterns. What is the justification of this principle ?

State the principle of conservation of energy.

Statement I : The principle of superpositions states that amplitudes , velocities , and , accelerations of the particles of the medium due to the simultaneous operation of two or more progressive simple harmonic waves are the vector sum of the separate amplitude , velocity and acceleration of those particles under the effect of each such wave acting alone in the medium Statement II : Amplitudes , velocities and accelerations are linear functions of the displacement of the particle and its time derivates.

Can we apply the principle of superposition to both types of waves ?

State the principle of floatation.

Many interesting wave phenomenon in nature cannot just be described by a single wave, instead one must analyze complex wave forms in terms of a combinations of many travelling waves. To analyze such wave combinations, we make use of the principle of superposition which states that if two or more travelling waves are moving through a medium and combine at a given point, the resultant displacement of the medium at that point is sum of the displacement of individual waves. Two pulses travelling on the same string are described by y_(1)=(5)/((3x-4t)^(2)+2) and y_(2)=(-5)/((3x+4t-6)^(2)+2) The time when the two waves cancel everywhere
