Question
Interference fringes from multiple sources of light can only be formed if the sources of light are: (Select most correct response.)Select one:a.monochromatic.b.polychromatic.c.coherent with each other.d.not coherent with each other.e.of no specific type. (Any light sources will combine to produce fringes.)
Solution
The most correct response is c. coherent with each other.
Interference fringes from multiple sources of light can only be formed if the sources of light are coherent with each other. This means that the light waves from the different sources must maintain a constant phase difference. This is necessary for constructive and destructive interference to occur, which is what creates the interference
