Question

Which of the following phenomenon is/are seen due to superposition of waves
1. Stationary wave
2. Beat
3. Interference
4. All of the above​

Answer 1

Answer:

Correct option is 4 (All of the above)

Explanation:

Superposition of wave:- When two or more waves are associated in order to form a new wave then that phenomenon is known as superposition of waves.

* Superposition wave principal is valid for all waves means it is valid for electromagnetic wave and also valid for mechanical waves.

* This principal is valid for low amplitude waves not for those which have very large amplitude.

* No any wave will affect motion to other it means more than two waves can transverse in the same medium.

Definition of the given options in terms of superposition waves:-

1. Stationary wave-: It is seen when identical waves are in opposite direction.

2. Beat:- It is the temporary intensity pattern and are seen when there will be same frequency of two superposition waves in the same direction.

3. Interference:- It is seen when there will be two superposition equal frequency with nearly equal amplitude

Answer 2

Answer:

4) All the above .

For other information:

Stationary wave : A standing wave is also known as stationary wave .stationary waves are produced by the superposition of two progressive waves of equal amplitude and frequency , traveling with same speed of the opposite side .

Beat : It is an Acoustic wave. With turning instruments that can produce sustained tones beats can be readily recognised .

Interference:interference is a phenomenon in which two waves superpose to form a resultant wave Greater , lower or the same amplitude.
