An X-ray tube operates at 100 kV. The maximum speed of electrons striking the anticathode is ( )
举一反三
- The momentum of photons corresponding to the minimum wavelength emitted from x-ray tube whose operating voltage is 120 kV is ( )
- The surface of a picture tube upon which the electrons produce the picture is called the screen.
- What is the maximum speed Titanic could reach?
- A metal surface illuminated by 8.5×1014 Hz light emits electrons whose maximum energy is 0.52 eV. The same surface illuminated by 12.0×1014 Hz light emits electrons whose maximum energy is 1.97 eV. The work function of the metal is ( B )
- The speed in which light travels is said to be the maximum in the universe.( )
