Relationship between say an opening and the wavelength

Click For Summary
SUMMARY

The relationship between the size of an opening and the wavelength of a wave is critical in understanding diffraction. Longer wavelengths, such as those used in AM radio, experience greater diffraction compared to shorter wavelengths like FM radio. This phenomenon explains why AM signals can better navigate obstacles like hills. The size of the opening does influence diffraction, but the primary factor is the wavelength itself.

I just have a basic question about waves and diffraction because i am not really clear on that part.

What is the relationship between say an opening and the wavelength. For example i am not sure if there is a smaller opening with a large wavelegnth, will a lot of diffraction occur.

With my limited knowledge I can tell you this much: longer wavelengths cause more diffraction. This is why AM often works better around hills and such than FM--AM has longer wavelength. As for the size of the hole, I don't know for sure but I think that that is not very important--don't trust me for sure though.
