Ray optics is valid when-xA0-characteristic dimension are-xA0-much larger than wavelength of light - The size of obstacle must be much larger than the wavelength of light- If wavelength is comparable to the size of object- then diffraction could happen- but it cannot be explained using ray optics- it will require wave theory of light-xA0-
