Can anyone tell me the difference between interference in double slit's and single slit diffraction?
Interference and diffraction are two phenomena that occur when waves interact with each other. Interference refers to the interaction of two or more waves that results in either constructive or destructive interference, while diffraction refers to the bending of waves around obstacles or through small openings. In other words, interference is the result of superposition of waves, while diffraction is the result of the spreading of waves.
Both interference and diffraction involve the interaction of waves, and they both result in changes in the amplitude and/or direction of the waves. They are also both examples of wave properties, and can be observed in various types of waves, such as light, sound, and water waves.
An example of interference is when two waves of the same frequency and amplitude meet and create a new wave with a larger amplitude (constructive interference) or cancel each other out (destructive interference). An example of diffraction is when light passes through a narrow slit and spreads out, creating a pattern of bright and dark fringes on a screen behind the slit.
The main difference between interference and diffraction is that interference creates a pattern of bright and dark fringes, while diffraction creates a pattern of bright and dark spots. This is because interference involves the superposition of waves, while diffraction involves the bending of waves around obstacles or through small openings.
Interference and diffraction have many practical applications in various fields. For example, they are used in the study of light and optics to create diffraction gratings for spectrometers, and in the study of sound to create diffraction patterns for acoustic lenses. In engineering, they are used to design and optimize the performance of antennas and other wave-based systems. In medicine, they are used in techniques such as X-ray crystallography to study the structure of molecules.
