Light of wavelength 1 illuminates a double slit, and interference fringes are observed on a screen behind the slits. When the wavelength is changed to wavelength 2 the fringes move farther apart. What is the relationship between wavelengths 1 and 2.
Added by Heather G.
Step 1
In a double-slit experiment, the position of the interference fringes on the screen is determined by the wavelength of the light used. The distance between the fringes (also known as fringe spacing) is directly related to the wavelength. Show more…

In a double-slit interference experiment, assuming that the distance from the location of the double slit to the location of the screen remains fixed, explain what happens to the double-slit interference pattern that appears on the screen if we: (a) increase the wavelength of the laser illuminating a particular, fixed double-slit (b) decrease the separation of the double-slit (i.e., replace the original double slit with a smaller-separation double-slit) while keeping the illumination unchanged.

In Young’s experiment, coherent light passing through two slits (S1 and S2 ) produces a pattern of dark and bright areas on a distant screen. If the wavelength of the light is increased, how does the pattern change? Explain why the answer is that "The bright areas move farther apart."
