Q6: Compare spacing patterns of re and blue light
At separate time, red light and blue light pass through the same two narrow slits, and each forms an interference pattern on the screen represented above. How do the spacings of the bright fringes in the two patterns compare? The red fringes are spaced farther apart than the blue fringes are, since the wavelength of red light is larger than blue light. λ =(dx)/L =>x = (λL)/d
