Q38 - How do diffraction effects show up?

Related QuestionsWhat is the diffraction of light?
FAQThe diffraction of light occurs when light bends around the boundaries of an object attempting to create a shadow. When light is sent through an opening that is wider than the wavelength of the light, a clear and distinct shadow is formed. However, if the light needs to pass through a very narrow opening, it bends around the edges of the opening and a fuzzy shadow is created. Diffraction occurs with all types of waves, but can be most often and easily seen with light.

Related QuestionsQ21. What is diffraction?
Frequently Asked Questions regarding lenses - photo.netWhen a beam of light passes through any aperture it spreads out. This effect limits how sharp a lens can possibly be. The diffraction is caused by the limiting of the beam to the size of the aperture, not primarily by sharp edges of the aperture. Even if one made a "soft edged" aperture that faded slowly from clear to opaque, there would still be diffraction, and the size of the central part of the diffraction pattern would not change much compared with the sharp-edged case.
Related QuestionsQ38: What are Tethers? Can I use one with my car/carseat?
Child Carseat Safety FAQTethers are straps that prevent the top of a carseat from moving forward in a crash. They may also increase overall stability.
