10. A beam of green laser light is diffracted by a single slit of width 0.40 mm. The diffraction patter is formed on a wall 2.00 m beyond the slit. The second order minimum is 6.0 mm from the centre of the central maximum.a) Find the wavelength (in nm) of the laser light.b) Calculate the fractional intensity I/lo at a point on the screen 4.5 mm from the centre of the central maximum.c) Sketch a graph of the intensity as a function of y, the position on the wall
