Word Meaning Remarks
Ray optics Study of light using ray model.
Rayleigh criterion Two optical images are separable if central bright spot of one image falls on first dark band of second.
Real image Optical image at which rays from object converge.
Receiver Device that detects electromagnetic waves.
Reference level Location at which potential energy is chosen to be zero.
Reference point Zero location in a coordinate system or frame of reference.
Refraction Change in direction of light ray when passing one medium to another.
Refractive index Ratio of speed of light in vacuum to that in the medium.
Resistance Ratio of potential difference across device to current through it.
Resistance force Force exerted by a machine.
Resistor Device designed to have a specific resistance.
Responding variable Variable that changes as result of change in manipulated variable.
Rest energy Energy due to mass of object; E= mc^ 2.
Resultant Vector sum of two or more vectors.
Right -hand rules Used to find force on current or moving particle in magnetic field; used to find direction of magnetic field caused by current or of induced EMF.
