threshold frequency造句
例句與造句
- This frequency is called the " threshold frequency ".
- EM radiation above a threshold frequency will get through-this is somewhere in the radio region.
- A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect.
- For any particular material, there is a threshold frequency that must be exceeded, independent of light intensity, to observe any electron emission.
- Is there a cheap material with a photoelectric threshold frequency in the blue-violet ( or near-ultraviolet ) range ? talk ) 20 : 57, 10 June 2012 ( UTC)
- It's difficult to find threshold frequency in a sentence. 用threshold frequency造句挺難的
- Different points in the visual system have very different critical flicker fusion rate ( CFF ) sensitivities; the overall threshold frequency for perception cannot exceed the slowest of these for a given modulation amplitude.
- One photon of light above the threshold frequency could release only one electron; the higher the frequency of a photon, the higher the kinetic energy of the emitted electron, but no amount of light ( using technology available at the time ) below the threshold frequency could release an electron.
- One photon of light above the threshold frequency could release only one electron; the higher the frequency of a photon, the higher the kinetic energy of the emitted electron, but no amount of light ( using technology available at the time ) below the threshold frequency could release an electron.
- The sudden cut-off below the threshold frequency indicates that it isn't a continuous wave of light which is " energizing " the electrons, rather it is a single particle of light which is energizing a single electron; below the threshold frequency, no single photon has enough energy to excite the electron to leave its orbit.
