Answer:
hey dear good evening,
Explanation:
Single Slit Amplitude Construction
Under the Fraunhofer conditions, the wave arrives at the single slit as a plane wave. Divided into segments, each of which can be regarded as a point source, the amplitudes of the segments will have a constant phase displacement from each other, and will form segments of a circular arc when added as vectors. In this way, the single slit intensity can be constructed.
Answer:
Explanation:
Light is interesting and mysterious because it consists of both a beam of particles, and of waves in motion.
WAVE PARTICLE DUALITY:
All carriers of energy and momentum, such as light and electrons, propagate like a wave and exchange energy like a particle.
It wasn't until the 19th century that convincing evidence was found showing that light behaves like waves.
Before reading on, you may wish to review some wave terminology.
The key to understanding why light behaves like waves is in INTERFERENCE and DIFFRACTION.
Interference and Diffraction are the phenomena that distinguish waves from particles: waves interfere and diffract, particles do not.
Light bends around obstacles like waves do, and it is this bending which causes the single slit diffraction pattern.
Some assumptions must be made for this description of the single slit diffraction pattern:
The slit size is small, relative to the wavelength of light.
The screen is far away.
Cylindrical waves can be represented in 2D diagrams as cicular waves.
The intensity at any point on the screen is independent of the angle made between the ray to the screen and the normal line between the slit and the screen (this angle is called T below). This is possible because the slit is narrow.
