This is the type of reaction that takes place at the sun to produce solar energy.
Ultraviolet radiation R T = R + R 2 + R 3 This are short waves with higher frequency that visible. It is this element of the sun s radiation that makes humans susceptible to sunburn and skin cancer. Formula to find total resistance in a series circuit. Spectra Red Shift Nebula This is the plural of spectra. This the manifestation of the Doppler Effect that involves a spectral shift because a star is moving away from the observer. This is an interstellar cloud of gas and dust. volt This is the SI unit for potential difference. It is equivalent to.0 J C. Gravitational field Transformer Electric current Infrared radiation Direct current Voltmeter Ammeter armature This is a sphere of influence that is caused by any object due to its mass. It can apply a force of attraction to any other object with mass within the field. This is a AC device that can step up or step down the voltage between the primary and secondary coils by changing the number of loops. This is the flow of electrons through a conductor. This is EMR that is slightly longer λ than visible. It sends the remote control signal to your TV set. This type of current is present when the charges go directly from the negative electrode to the positive one through the circuit. It is abbreviated as DC. This is an electrical device that measures the potential difference between two points in a circuit. This is an electrical device that measures the current flowing through a circuit. This is the section of an electric motor that rotates. Electromagnetic Radiation (EMR) This is the type of wave that does not require a medium. It is propagated by perpendicular changing electric and magnetic fields.

This is an EMR receiver. frequency Ionizing radiation Gamma radiation V = IR Refraction Field lines Red giant Continuous voltage Coulomb commutator This is a measure of the number of waves to pass by per second. It is measured in Hz. This is the result of radioactive decay. It includes particle and photons (alpha, beta and gamma) that can penetrate living tissue ionize atoms of cells and kill or cause mutation. This is the shortest λ, higher f waves in the EMR. They are extremely dangerous. This is the formula for Ohm s Law. This is the bending of light waves due to a change in medium. Moving from a less dense material to a more dense (air to water) will slow the light waves and cause them to bend towards the normal. These are lines that are drawn around an object to show the direction and strength of the object s field. They may represent a magnetic field, gravitational field or electric field. This is a star of great size and age that has a low surface temperature. This include the complete ROYGBIV, it is produced when a glowing solid emits light that passes through a triangular prism. This is also known as potential difference. It represents the difference in energy per coulomb of charge. This is the SI unit for charge. It is equal to.0 A. s. One electron has the charge of.60 x 0-9 C. This is the part of an electric motor or generator that is found on the armature, that provides the electric current. If found on a DC device it will be the split ring type.
Alternating current This type of current is present when the charges change direction several times per second while present in the circuit. It is abbreviated as AC. hertz (Hz) This is the SI unit for frequency. It the equivalent to s. Schematic diagram Primary coil This is aka a circuit diagram. It uses symbols to detail the components and nature of a circuit. This is input side of a transformer. Transverse wave Doppler effect X-rays Reflection Visible Absorption (dark-line) Multiwavelength astronomy Neutron star Insulator Solar wind This is a wave produced by a disturbance in the medium that is perpendicular to the direction of travel. This is the apparent shift in frequency of waves due to relative motion between the source and the receiver of the wave. This are fairly short waved, high frequency EMR. They are used to penetrate human tissue to scan for broken bones. This is when a wave makes contact with a boundary, and bounces off. This is the part of the EMR that our human eyes can see. It include the colours: ROYGBIV. This is a that looks like a continuous with a series of dark lines on it. It is produced when the white light produced by a glowing solid passes through a cool gas and then a triangular prism. This is the science of studying several different wavelengths of EMR emitted in objects in space. A super-dense star consisting mainly of neutrons formed at the last stage in the star development of intermediate-mass stars. This is a material that will allow not electrons to flow throw it easily. Rubber and glass are examples. Streams of high speed, ionized particles ejected from the sun. They normally consist of electrons, protons and helium nuclei.

This is a push or pull effect applied to a charged object by the electric field of another charge or by charged plates. This is energy that is available to the movement of electrical charges. This is a device in a circuit that contains resistance and uses electric energy in a circuit. Is the amount of energy used or work done per unit time. It is measured in watts.

Radiation therapy Blue shift Diffraction Emission (bright-line) This is the medical use of ionizing radiation to treat disease like cancer. This the manifestation of the Doppler Effect that involves a spectral shift because a star is moving towards the observer. This is the wave property that involved the bending of light due passing next to a boundary. With light a spectra can be produced by directing light waves through a diffraction grating.
