crossword puzzle – Flashcards

the process of removing excess charge by touching an object to earth

in any periodic motion the amount of time required for an object to repeat on complete cycle of motion

a diverging lens, thinner at its middle than at its edges, that spreads out light rays passing through it, produces a virtual upright image that is smaller than the object

states that the angle a reflected ray makes, as measured from the normal to a reflective surface, equals the angle the incident ray makes, as measured from the same normal

a material such as copper through which charge will move easily

the image defect of a spherical mirror that does not allow parallel light rays far from the principal axis to converge at the focal point, and produces an image that is fuzzy, not sharp.

in any periodic motion, the maximum distance an object moves from equilibrium

the high point of a wave

the highness or lowness of a sound wave which depends on the frequency of vibration

a scattered fuzzy reflection produced by a rough surface

the number of complete oscillations that a wave makes each second; is measured in hertz, Hz

the bending of a light around a barrier

the change in the frequency of sound caused by the movement of either the source, the detector, or both the detector and the source

results from the superposition of two or more waves; can be constructive or destructive

wave displacements in the same direction

waves with equal but opposite amplitudes

the product of a rotating objects moment of inertia and its angular velocity measured in kilogram*meters squared/second

a mirror that reflects light from its outwardly curving surface and produces an upright, reduced virtual image

light from two or more sources, whose additive superposition produces smooth wave fronts

states that the force between two charges varies directly with the product of their charge and inversely with the square of the distance between them
