Question

Create a table comparing and contrasting constructive and destructive interference .

Answer 1

Constructive interference:-

1. The constructive interference takes place, when the amplitude of the two or more waves combines to form the resultant wave with more amplitude.

2. The phase difference between the waves during the constructive interference is,

`\varnothing=(n\pi)/(2)`

where n is the even number.

3. In the constructive interefernce, the bright fringes are observed.

Destructive interference:-

1. The destructive interference takes place when the ampltude of two or more wave combines to form the resultant wave with less amplitude.

2. The phase difference between the waves during the destructive interference is,

`\varnothing=(n\pi)/(2)`

where n is the odd number.

3. In the destructive interference, the dark fringes are formed.
