Nonselective scattering is caused by particles that are much larger than the wavelength of the scattered radiation. （ ）
举一反三
- 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
- In a Compton scattering experiment, a photon of energy E is scattered from an electron at rest. After the scattering event occurs, which of the following statements is true? A: The frequency of the photon is greater than E/h. B: The energy of the photon is less than E. C: The wavelength of the photon is less than hc/E. D: The momentum of the photon increases.
- Mie scattering tends to be greatest in the lower atmosphere (0 to 5 km), where larger particles are abundant. （ ）
- After Compton scattering, the scattered x-ray has_______. A: Higher energy B: Higher velocity C: Less mass D: Longer wavelength
- The population of China is （）the United States. A: much larger than that of B: moremore larger than that of C: much larger than D: moremore larger than
