Light from sodium lighting passes through a single slit, then through double slit system and is projected on a screen. The separation distance between the slits of the double slits is 1.00mm. The screen is placed at 1.0m from the double slits system and the sodium light lighting has a wavelength of 5.9x10-5cm
a)Calculate the separation distance between two consecutive bright fringes on the screen.(0.59mm)
b)If the sodium lighting is replaced with a BLUE monochromatic source, what will happen to the image pattern on the screen?
