Answer

Light of shorter wavelengths is scattered much more than light of longer wavelengths. The amount of scattering is inversely proportional to the fourth power of the wavelength. This is known as Rayleigh scattering.

Answer

Understanding Rayleigh Scattering
Rayleigh scattering is a phenomenon that describes how light or other electromagnetic waves scatter when they encounter particles much smaller than the wavelength of the light.

Key Points about Rayleigh Scattering:

Wavelength Dependency: The intensity of Rayleigh scattering is inversely proportional to the fourth power of the wavelength. This means shorter wavelengths (like blue light) scatter significantly more than longer wavelengths (like red light).
Formula: The scattering intensity (I) can be expressed as:
I ∝ 1/λ⁴
where λ is the wavelength of the light. This explains why the sky appears blue; blue light is scattered more than other colors.
Particles Size: Rayleigh scattering occurs when the size of the scattering particles (like molecules in the atmosphere) is much smaller than the wavelength of light, typically less than 1/10th the wavelength.

Applications of Rayleigh Scattering:

Atmospheric Science: It helps explain various atmospheric phenomena, including why the sky is blue and sunsets appear red and orange.
Optical Devices: Rayleigh scattering is significant in the design of various optical instruments and imaging technologies.

Conclusion
In summary, Rayleigh scattering directly relates scattering and wavelength by demonstrating that shorter wavelengths are scattered more than longer ones. This fundamental principle is essential in fields such as physics, meteorology, and optical engineering.
