Electromagnetic waves are transverse waves that travel through space at the speed of light.
Radio waves have the longest wavelength, while gamma rays have the shortest wavelength.
Infrared radiation has a longer wavelength than visible light but shorter than radio waves.
Ultraviolet radiation has a shorter wavelength than visible light but longer than X-rays.
X-rays have a shorter wavelength than ultraviolet radiation but longer than gamma rays.
Gamma rays have the shortest wavelength and highest frequency among all types of electromagnetic radiation.
Visible light can be seen by the human eye, while other forms of electromagnetic radiation cannot.
Different colors of light correspond to different frequencies or wavelengths.
The energy of an electron is directly proportional to its velocity (e = ½ mv^2).
When an electric current flows through a wire, it creates a magnetic field around the wire.
A changing magnetic field induces a potential difference across a conductor.
The color red corresponds to lower energy photons with longer wavelengths, while violet corresponds to higher energy photons with shorter wavelengths.
Higher frequencies carry more energy per photon compared to lower frequencies.
The energy carried by an electromagnetic wave is proportional to its frequency (E = hf).
Electric fields are created when there is an imbalance between positive and negative charges.
Electrons are negatively charged particles that orbit around the nucleus of atoms.
Different colors of light correspond to different energies due to their varying frequencies.
A charged object will create an electric field around it that exerts forces on nearby objects.
When an atom gains or loses electrons, it becomes ionized.
An alternating voltage produces an alternating current that oscillates between positive and negative values.
An alternating voltage produces an alternating current.
Electricity is produced when moving charges create a magnetic field that interacts with another magnetic field.
Ionization occurs when an atom gains or loses one or more electrons, resulting in a net positive charge on the remaining protons and neutrons.
Electricity can flow along a path with no resistance if there are no obstacles in the way.
In a series circuit with multiple resistors, the total resistance is equal to the sum of individual resistances.
Increasing the speed of charged particles increases their kinetic energy.
In a parallel circuit with multiple resistors, the equivalent resistance is less than any single resistance.
Electric fields can be created by moving charges or changes in magnetic fields.
Magnetic fields are created when moving charged particles create a force on other charged particles.
An electromagnet produces a magnetic field when a current passes through a coil of wire.
An increase in temperature causes more collisions between molecules, resulting in increased thermal energy.
Magnetic fields are produced by moving charges or changes in electric fields.
Infrared radiation has a long wavelength and low frequency, making it less energetic than visible light.
When electrically charged objects move through space, they create magnetic fields.
Magnetism can be used as a force to attract or repel other magnets.
Ultraviolet radiation has a short wavelength and high frequency, making it more energetic than visible light.
An electron volt (eV) is a unit used to measure the amount of kinetic energy gained or lost by an electron as it moves through an electrical potential difference.
An electron volt (eV) is a unit used to measure the amount of kinetic energy gained by an electron as it moves through a potential difference of one volt.
A magnet has two poles - north and south - which always face opposite directions.
