Two coherent point sources `S_(1)` and `S_(2)` vibrating in phase emit light of wavelength `lambda`. The separation between the sources is `2lambda`. Consider a line passing through `S_(1)` and perpendicular  to line `S_(1) S_(2)`. Find the position of farthest and nearest minima. img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C02_S01_006_Q01.png" width="80%"
