I think it is Ultraviolet. The wavelength range of infrared is from 7*10^-7 to 10 ^-3 and ultraviolet is from 6*10^-8 to 4*10^-7 and since that he asked for significant diffraction then it should be the smallest wavelength which is ultraviolet.

IT DID NOT GIVE WAVELENGTHH!!!! IT SAID THIS IS A WIDTH THROUGH WHICH THEY PASS! AND IT SAID THAT THE WAVE DOES NOT DIFFRACT! THIS MEAN ITS WAVELENGTH HAD TO BE MUCH SMALLER THAN THE WIDTH! WHICH IS ULTRAVIOLET! god!

and sabrina please stop "enlightening" us with your teacher's answers, keep it to yourself  
AS u wish. i thought i was helping someone but i didnt know that i was anoying anyone. i m sorry

The wavelength was not given, it was the width of the gap.
