Thomas Young's sketch of two-slit diffraction, which he presented to the Royal Society in 1803 Sound waves can diffract around objects, this is the reason we can still hear someone calling us even if we are hiding behind a tree.ĭiffraction can also be a concern in some technical applications it sets a fundamental limit to the resolution of a camera, telescope, or microscope. Ocean waves diffract around jetties and other obstacles. All these effects are a consequence of the fact that light is a wave.ĭiffraction can occur with any kind of wave. A shadow of a solid object, using light from a compact source, shows small fringes near its edges. Diffraction in the atmosphere by small particles in it can cause a bright ring to be visible around a bright light source like the sun or the moon. This principle can be extended to engineer a grating with a structure such that it will produce any diffraction pattern desired the hologram on a credit card is an example. The most colorful examples of diffraction are those involving light for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern we see when looking at a disk. The effects of diffraction can be readily seen in everyday life. 5.1 Diffraction from an array of narrow slits or a gratingĮxamples of diffraction in everyday life.5 Quantitative description of diffraction.4 Qualitative observations of diffraction.1 Examples of diffraction in everyday life.While diffraction always occurs, its effects are generally most noticeable for waves where the wavelength is on the order of the feature size of the diffracting objects or apertures. Diffraction even occurs with matter – according to the principles of quantum mechanics, any physical object has wave-like properties. It occurs with any type of wave, including sound waves, water waves, electromagnetic waves such as visible light and radio waves. The intensity pattern formed on a screen by diffraction from a square apertureĭiffraction refers to various phenomena associated with wave propagation, such as the bending, spreading and interference of waves passing by an object or aperture that disrupts the wave.
