The amplitude of a wave is represented by the length of a “vector” on an Argand diagram. The phase of the wave is represented by the angle of the vector relative to the
Define amplitude, frequency, period, wavelength, and velocity of a wave; Relate wave frequency, period, wavelength, and velocity; Solve problems involving wave properties
Incoherent generally gives better image quality: no ringing artifacts. no speckle. higher bandwidth (even though higher frequencies are attenuated because of the MTF roll-off) However, incoherent imaging is insensitive to phase objects.
Wave Optics (physical optics) treated in the second half of the class: - Emphasis on analyzing interference and diffraction - Gives more accurate determination of light distributions
11 Ιαν 2023 · We begin our study of waves in this first unit of Physics 7C with an introduction to waves and then a thorough development of the harmonic plane wave model, which we will use extensively to model and understand a wide variety of wave phenomena.
An interactive simulation to explore and learn about the properties, behavior, and effects of waves.
Below is a model of a wave. A wave’s crest is its highest point, and its trough is its lowest point. A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave.
