Interference and Diffraction02:18

Interference and Diffraction

49.7K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Radiation: Applications

1.3K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Dual Nature of Electromagnetic (EM) Radiation

2.8K
Electromagnetic (EM) radiation consists of electric and magnetic field components oscillating in planes perpendicular to each other and mutually perpendicular to radiation propagation through space. EM radiation can be classified as a wave, characterized by the properties of waves such as wavelength (denoted as λ) and frequency (represented by ν).
Wavelength is the distance between two consecutive peaks (the highest point) or troughs (the lowest point) in the wave. Frequency is the...

Interaction of EM Radiation with Matter: Spectroscopy

2.4K
Electromagnetic (EM) radiation can be considered an oscillating electric and magnetic field propagating through a medium that can interact with matter in its path. The electric field in the radiation can interact with electrical charges in the atoms or molecules in the matter. On the other hand, the magnetic field can interact with the magnetic field in the atomic nucleus. The study of the interaction between electromagnetic radiation and matter is termed spectroscopy. Spectroscopy is the study...

Radiation Pressure: Problem Solving01:09

Radiation Pressure: Problem Solving

519
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

    Area of Science:

    • Optics and Photonics
    • Wave Phenomena
    • Coherence Theory

    Background:

    • Spatial coherence is crucial for many optical applications.

    • Experimental verification of coherence changes.
    • Investigation across various wave superposition scenarios, including Mie scattering.

    Main Results:

    • Superposition of partially correlated waves leads to significant changes in coherence.
    • Two strongly correlated sources can produce a field with near-zero point-pair correlation.
    • This anomalous coherence behavior is a general phenomenon in wave superposition.

    Conclusions:

    • The spatial coherence of light is not always preserved upon superposition.
    • Anomalous coherence changes challenge assumptions in optical system design.
