Urban haze, the scattering or absorption of light, is caused by fine particles.
举一反三
- The Tyndall effect is the result of scattering of light by sol particles.
- Nonselective scattering is caused by particles that are much larger than the wavelength of the scattered radiation. （ ）
- Scattering is the change in the direction of electromagnetic energy caused by ( ). A: Particles suspended in the atmosphere B: Water droplets C: Large molecules of atmospheric gases D: Dust
- When the diameter of the fine particles in the haze is 10 microns, it can directly enter the alveoli and bronchioles of the human body, stimulating the bronchoconstriction, affecting the ventilation function of the alveoli and causing hypoxia induced by the body.
- It ______ last week that the haze (雾霾)in Beijing caused many problems.
