The Tyndall effect is the result of scattering of light by sol particles.
举一反三
- Urban haze, the scattering or absorption of light, is caused by fine particles.
- What isthe essential characteristic of colloid? A: Tyndall effect B: Brownian motion C: Colloidal particles size ranges from1nmto 100nm D: colloidal particles charged
- Spontaneous Brillouin<br/>scattering is generated through the interaction between the input<br/>light field and the thermally<br/>fluctuating acoustical fields______ .The feature of this effect is that the frequency shift of the<br/>scattering light is dependent on the scattering angle and theacoustic<br/>velocity<br/>______ in<br/>the medium.
- Nonselective scattering is caused by particles that are much larger than the wavelength of the scattered radiation. （ ）
- The amount of scattering that occurs depends on the ( ). A: Size of particles B: Radiation wavelength C: Quantity of particles D: How deep the energy passes through the atmosphere
