WebConsider a light wave fallingon a slit of apertureawhich is comparable to its wavelength Itis diffracted through an angle andits diffraction width increases with the ... WebRay optics, also known as geometrical optics, is the study of simple properties of light and optical instruments by assuming that light travels in a straight line. Ray optics deals with the geometry of the light. Light always travels in a straight line and the direction in which the light rays propagate is called the ray of light.

WebIn the ray optics regime, the radiation incoming across the screen effectively behaves as a particle. On the screen, only observers located in correspondence to the two slits in x 1 and x 2 would receive a signal. In particular, an observer located at x = 0 would not receive any signal, i.e. the width of the first peak can be neglected in this ...
