These pits are placed in a row of the same width and at equal distance. Recorded data on CD is stored in microscopic pits of different lengths which carries information in the CD. Compact Disc (CD) also resembles the same kind of colours when viewed from different angles. Well, rainbow is formed because water droplets in the atmosphere separate white light into different colours of the rainbow. So almost all of you have seen a rainbow formation on rainy days.

Many a time you may have seen diffraction in your life but the problem is we may not notice these little things which are created due to some of the most interesting phenomena of science and diffraction is one of them. Examples and applications of diffraction: Now you know about diffraction and let’s know some of the real-life examples and application of diffraction. All kind of waves such as water waves, gravitational waves and electromagnetic waves all waves in spectrum such as radio waves, x-ray, gamma rays etc. This effect also occurs when light waves travel through a medium of different refractive index. Diffraction is tend to be used when there are many sources of wave and interference is used when only a few wave sources are considered. Now you may have heard about interference and it’s kinda same like diffraction but wait don’t get confused between both of them.ĭiffraction and interference are closely related but they both don’t have an exact meaning. According to this principle, every point on a wave behaves like a source. Phenomena of diffraction is described from the Huygens-Fresnel principle.
