Final answer:
The interference of 0.59 refers to the distance between adjacent bright fringes in an interference pattern.
Step-by-step explanation:
The interference of 0.59 refers to the distance between adjacent bright fringes in an interference pattern. In this case, the interference pattern is created by a He-Ne laser light passing through two slits. The slits are 0.031 mm apart and the interference pattern is projected on a screen 10.0 m away. By calculating the interference, we can determine the distance between adjacent bright fringes.
