A demodulator's primary function is to convert the modulated signal back to its original form so that the information can be retrieved.

A diode acts as a current rectifier, allowing current to flow in one direction while blocking it in the opposite direction.

A diode is primarily used for rectification, allowing current to flow in one direction only.

The role of a moderator in a nuclear reactor is to slow down neutrons, making them more likely to induce fission in the fuel.

A p-n junction creates a depletion region which is essential for the operation of diodes and transistors.

In a transistor, the semiconductor material is used to amplify current, allowing small input signals to control larger output signals.

Transistors can perform multiple functions including switching, amplification, and signal modulation.

A transponder receives signals at one frequency, amplifies them, and then converts them to another frequency for transmission back to Earth.

Temperature increases the number of charge carriers in semiconductors, thus increasing their conductivity.

The Heisenberg Uncertainty Principle states that it is impossible to simultaneously know the exact position and momentum of a particle, which is fundamental in quantum mechanics.

The Heisenberg Uncertainty Principle states that the position and momentum of a particle cannot be simultaneously known with arbitrary precision.

The photoelectric effect was crucial in the development of quantum mechanics, as it provided evidence for the quantization of energy.

Ionization energy is defined as the energy required to remove an electron from an atom in the gas phase.

Threshold frequency (ν₀) = Work function (Φ) / h = 4.5 eV / (4.14 x 10^-15 eV·s) = 5.4 x 10^14 Hz.
