A viewing screen is separated from a double-slit source by 1.3 meters. The distance between the two slits is 0.020 mm. The second-order bright fringe (m = 2) is 2.5 cm from the center line. (a) Determine the wavelength of the light and (b) Calculate the distance between adjacent bright fringes

please help. also, by using the information on the figures, determine a/wavelength for figure III and figure IV. each ratio as an integer.

Draw a diagram. Determine the wavelength and frequency of the light emitted from the source.

Consider the following relative intensity graph for a double-slit experiment. The wavelength of the light used was λ = 633 nm. 1 0.8 0.6 0.4 0.2 0 0 (radians) Determine the width of the slits and the distance between the slits. Clearly indicate which features of the graph you are using to make your determination. You may have already noticed that the maxima are (approximately) 0.01 radians apart. except that there are no maxima at 8 = 0.05 radians or = 0.10 radians. How can you account for these "missing" maxima? (Hint: Consider how the relative intensity graph would be different if the width of the slits were decreased.)
