Two wave sources are oscillating in phase . Each source produces a wave of wavelength lemda . The two waves from the sources meet at point X with a phase difference of 90° . What is a possible difference in the distances from the two wave sources to point X ?

first x+x = 2x
2x = 90°
x = 90°/2
x = 45°
so, the different in the stage frim two point is x.
2x = 90°
x = 90°/2
x = 45°
so, the different in the stage frim two point is x.
