Honors Physics E & M review

Electric Field

Region around a charged object where other charged objects would experience a force.

Electric Potential Energy

Energy a charge has due to its position in an electric field.

Electric Potential

Work needed to bring a unit positive charge from infinity to a point in an electric field.

Induction

Charging a neutral object by bringing a charged object near it without direct contact.

Conduction

Charging an object by direct contact with another charged object.

Polarization

Separation of charges within an object without transferring them.

Friction

Charging by rubbing two materials together, transferring electrons.

Nature of Images in Mirrors and Lenses

Concave forms real/virtual images based on object position, convex forms virtual images.

Resonance

Amplification of vibrations when external force frequency matches object's natural frequency.

Inverted Wave

Wave with a phase shift of 180 degrees, changing crests to troughs.

Snell's Law

Describes light bending at a medium boundary based on angles of incidence and refraction.

Total Internal Reflection

Reflection of light back into a higher refractive index medium due to a critical angle.

Additive Colors and Light

Mixing colored lights like red, green, and blue to produce white light.

Color Subtraction to Pigments

Mixing pigments like cyan, magenta, and yellow to subtract wavelengths and produce colors.

Doppler Effect

Change in wave frequency or wavelength due to motion relative to the wave source.

Focal Point

Point where light rays converge or appear to diverge in mirrors or lenses.
