The resultant amplitude in interference with two coherent source depends upon –

As a result of interference of two coherent sources of light, energy is

As a result of interference of two coherent sources of light, energy is

What is the importance of coherent sources in case of interference of light ? How are coherent sources produced ?

In interference pattern, using two coherent sources of light, the fringe width is …… .

Why there is no interference pattern observed when two coherent sources are placed far apart?

Why interference pattern not detected when two coherent sources are far apart.

Interference fringes are obtained due to interference of waves from two coherent sources of light having amplitude a_(1) and 2a_(1) . The ratio of maximum and minimum intensities in the interference pattern will be -
