Summary
Cloud iridescence, unlike coronas, is explained by light interference. This phenomenon arises from the interaction between diffracted and transmitted light within water droplets, creating colorful cloud displays.
Area of Science:
- Atmospheric optics
- Cloud physics
- Light scattering phenomena
Background:
- Near-forward scattering of sunlight causes optical phenomena in clouds.
- Cloud coronas result from light diffraction.
- The cause of cloud iridescence remains less understood.
Purpose of the Study:
- To propose a mechanism for cloud iridescence.
- To explain the optical processes behind colorful cloud patches and bands.
Main Methods:
- Theoretical analysis of light interaction with water droplets.
- Modeling light diffraction and transmission through spherical water particles.
Main Results:
- Iridescence is attributed to the interference of diffracted and transmitted light.
- This interference pattern explains the observed colors in cloud iridescence.
Conclusions:
- Interference between diffracted and transmitted light is the primary cause of cloud iridescence.
- This finding clarifies a previously ambiguous atmospheric optical phenomenon.

01:28Irrotational Flow
1.0K
Irrotational flow is characterized by fluid motion where particles do not rotate around their axes, resulting in zero vorticity. For a flow to be irrotational, the curl of the velocity field must be zero. This imposes specific conditions on velocity gradients. For instance, to maintain zero rotation about the z-axis, the gradient condition:

02:18Interference and Diffraction
52.8K
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.

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

01:26Influence of Earth's Curvature and Atmospheric Refraction on Leveling
1.0K
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance. Over a...

01:05Doppler Effect - II
4.9K
The Doppler effect has several practical, real-world applications. For instance, meteorologists use Doppler radars to interpret weather events based on the Doppler effect. Typically, a transmitter emits radio waves at a specific frequency toward the sky from a weather station. The radio waves bounce off the clouds and precipitation and travel back to the weather station. The radio frequency of the waves reflected back to the station appears to decrease if the clouds or precipitation are moving...

01:12Precipitation Processes
6.3K
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...
