![]() ![]() So let’s understand the relation between diffraction and holograms. ![]() Hologram projection is also an example of diffraction and you may have seen one. So, what comes inside your mind when you hear the word ” hologram”, it’s sound cool to me and this phenomena is pretty cool. P.s:- Microscopic pits means where data on a compact disc is stored in binary format (1 or 0) inside a CD. This forms a diffraction grating on the CD mirror surface. 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. Larger the wavelengths being diffracted, lesser will be the angle of diffracted light.Phenomena of diffraction is described from the Huygens-Fresnel principle. The amount of diffraction depends on so many factors like the wavelength of fallen light. Sometimes we can observe pastel shades of blue, pink, purple, and green in clouds that are formed due diffraction of light from water droplets in the clouds. A good daily life example of this is the diffraction of sunlight by clouds that are often called by us as silver lining. These kinds of parallel lines are the diffraction patterns. As the fingers become close to each other we can see a series of dark lines parallel to the fingers. There are so many daily life examples for can be performed by holding our hand in front of a light source and slowly closing two fingers while observing the transmitted light in between them. It is defined as the bending of waves at the edges of an obstacle or through a slit into the region of geometrical shadow of the obstacle or slit.ĭiffraction of light is a phenomenon in which a light wave passes by a corner or edge of an obstacle through an opening called as a slit that is approximately having the size in order of or even smaller than that wavelength of light. Hint: Diffraction of light refers to the phenomena that occur when a wave of light encounters an obstacle or a slit generally.
