A beam of monochromatic light is incident on a single slit of width 0.650 mm. A diffraction pattern forms on a wall 1.25 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.34 mm. Calculate the wavelength of the light. nm

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
