How did u guyz do in phys p1 ?
mr.incredible:
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.
XaM!!:
@spy wavelength was given. n ya sabrina plz stop praising ur teacher.

and sabrina please stop "enlightening" us with your teacher's answers, keep it to yourself

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

r u really sure? maybe u have another varient. n that ques didnt said anythng about difraction. it only gave wavelength n askd which of the folowing have this wavelngth. maybe u hav another varient n ques r changd?
