The two sources above are emitting light coherently at a wavelength of 100 nanometers. The length from each source to the points labelled A-G are marked in nanometers. Using these lengths, l1 and l2, determine if the light at each point is experiencing constructive or destructive interference. And find the value for m at each point.
