Question

1. Two waves with same frequency are in superposition.b) What is the condition of the two wave when the interfered signal has the best visibility

Answer 1

When two or more electromagnetic waves interfere and occupy the same point the resultant wave is called superposition.

Explanation:

• A wave must possess ave-like properties such as quantum, mechanic, and electrical waves.
• The two waves must have the same phase difference in order to produce a superposition.
• To have the best visibility, the amplitude of the waves must be equitable to the sum of the powers.
