Absorption of Radiation01:05

Absorption of Radiation

1.1K
The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:

Schwarzschild Radius and Event Horizon

2.5K
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...

Pigmentation01:19

Pigmentation

4.0K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Changes in Skin Color: Clinical Perspectives

3.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Emission Spectra02:39

Emission Spectra

74.9K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Photoreceptors and Plant Responses to Light02:00

Photoreceptors and Plant Responses to Light

28.0K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

    Area of Science:

    • Atmospheric optics
    • Solar physics

    Background:

    • Solar eclipses cause unique illumination conditions.
    • Sunlit cloud tops and arctic sea ice near the umbra appear salmon-brown.

    Purpose of the Study:

    • To explain the observed salmon-brown coloration during solar eclipses.
    • To model the spectral characteristics of light during eclipses.

    Main Methods:

    • Utilizing a second-order scattering model.
    • Simulating photographic and satellite "true color" images from specific eclipses (2017, 2019).

    Main Results:

    • Limb reddening of solar light significantly contributes to the observed color.
    • Model simulations align with observed colors from flights and satellites.

    Conclusions:

    • Observed color changes during solar eclipses offer insights.
    • This phenomenon has potential applications in determining solar photospheric temperature profiles.
