A helium-neon laser produces light with a wavelength of 638 nm. When this light is shone through a double slit apparatus, an interference pattern is produced on a screen 2.0 m away, with the distance between the first and seventh nodal lines being 5.0 cm.
a) Determine the distance between the slits.
b) What is the maximum number of bright fringes that could possibly appear on the screen?
c) Draw a diagram that represents the situation.
