Definition
Proper noun: - John William Strutt, Third Baron Rayleigh: An English physicist and Nobel laureate. He is known for his work on the theory of sound, the scattering of light (Rayleigh scattering), the discovery of the noble gas argon (with Sir William Ramsay), and investigations into the density of gases. He served as the third Baron Rayleigh.
Usage Examples
- Proper noun:
- The Third Baron Rayleigh received the Nobel Prize in Physics in 1904 for his discovery of argon.
- Lord Rayleigh, the Third Baron Rayleigh, made fundamental contributions to acoustic theory.
- The phenomenon explaining why the sky is blue is named after the Third Baron Rayleigh.
Advanced Usage
- "Rayleigh scattering": The elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. This is the primary reason the sky appears blue.
- Rayleigh scattering, named for the Third Baron Rayleigh, is a key concept in atmospheric physics.
- "Rayleigh criterion": In optics, a criterion for the minimum resolvable detail through an optical instrument.
- The Rayleigh criterion defines the limiting resolution of a telescope.
