The following statement is correct () A. In terms of the expression E = hv of the material wave, the wavelength A and the frequency v are the physical quantities that describe the fluctuation of the material B. The polarization of light states that the state is merely waves C. The interference and diffraction of light indicate that light has a particle D. The photoelectric effect shows both the particle nature of the light and the fluctuation of the light 14. The following statement is correct () A. the discovery of natural radioactivity reveals the atomic structure B. Radiation is a very short wavelength of electromagnetic waves, and its penetrating power is weaker than that of the rays C. If you can measure the loss of quality in the process of small nuclear reactions, you can calculate the nuclear energy released in the nuclear reaction D. A deuteron (H) emits an electron while fusing with a tritium (H) to produce a helium nucleus (He) 15. The following physical phenomenon: the braking of the car on the straight road and the distance to a distance, and finally stop; Meteors fall and shine brightly in the night sky; The parachute dropped at a constant speed in the air.
