In an interference experiment, red light with a wavelength of 6.0 x 10 –7 m passes through a double slit. On a screen 1.5 m away, the distance between the 1st and 11th dark bands is 2.0 cm. (a) What was the separation of the slits? (b) What would the spacing be, between adjacent nodal lines, if blue light were used? (λblue = 4.5 x 10 –7 m)
