A narrow slit of width 0.025 mm is illuminated by a parallel beam of light. The diffraction pattern is observed through a telescope. It is found that to reach the first minimum, the telescope has to be rotated through `1^(@)24`' from the direction of the direct ray. Calculate the wavelength of light used.
