A negative resistance region evidenced in the Ep-Ip characteristic of a tetrode when dc screen voltage exceeds dc plate voltage. The negative slope of the plate current curve is due to the screens attractive secondary electrons from the plate when screen voltage exceeds plate voltage and the attendant reduction of plate current during the interval. What effect is mentioned above?

The reception and reproduction of radio signals by ordinary pieces of metal in contact with each other, such as sections of stovepipes. This occurs when rusty bolts, faulty welds, or mechanically loose connections within strong radiated fields near transmitter and produce intermodulation interference. The mechanically poor connections serve as nonlinear diodes. What effect is mentioned above?

The elastic scattering of photons by electron. Since the total energy and total momentum are conserved in the collisions, the wavelength of the scattered radiation is changed by an amount that depends on the angle of scattering, and part of the photon energy is transferred to electrons. This effect is called

The generation of acoustic waves, consisting of alternate regions of compression and refraction one half-wavelength apart, by a piezoelectric crystal vibrating in a longitudinal mode in a liquid. When a parallel beam of light sent through the liquid in a tank having plate-glass walls, the acoustic waves act as a diffraction grating that can be used to determine the velocity of sound in the liquid. This effect is called

When light falls on a light surface of an intermetallic semiconductor located in a magnetic field that is parallel to the surface, excess hole electron pairs are created. Those carriers diffuse in the direction of the light but are deflected by the magnetic field to give a current flow through the semiconductor that is at right angles to both the light rays and magnetic field. This is known as the
