Derive the conditions for bright and dark
fringes produced due to diffraction by a
single slit.
Answers
Explanation:
When light travels in air, it encounters various phenomena like interference, refraction, reflection and diffraction. When the light comes in contact with an obstacle, diffraction of light takes place.
When light passes through a small opening, comparable in size to the wavelength λ of the light, the wavefront on the other side of the opening resembles the wave. Let us know more about the diffraction of light and single slit diffraction that occurs when light travels through a single slit.
We can observe single slit diffraction when light passes through a single slit whose width (w) is on the order of the wavelength of the light. The diffraction pattern on the screen will be at a distance L >> w away from the slit. The intensity is a function of angle.
