Electromagnetic waves : waves sent through space that are created by electrical and magnetic fields.
Wavelength : the distance from any given point on a wave to the same point on the next wave in a series. It is usually measured from the crest of one wave to another.
Radiation : the transfer of heat through energy waves radiating directly from a heat source to the food. Fish under a broiler, toast in a toaster, and marshmallows over the glowing coals of a campfire are examples of heat transfer by _________.
Diverge : to go in different directions from a common starting point; to not hold together.
Refraction : the bending of a light ray as it passes from one medium to another medium of a different density.
Focal length : the distance from the center of a lens to the point where the light rays filtered through that lens converge.
Coherent : the description of light that is in phase – all the light waves are traveling in the same direction, with the same frequency, and at the same wavelength.
Incident rays : the optical rays that are traveling toward a surface.
Reflected rays : rays that have been “bounced” off a reflecting surface.
Angle of incidence : the angle that a ray of light striking a reflecting surface forms with another line that is perpendicular to the reflecting surface and a perpendicular line drawn to that surface at the point of incidence.
Angle of reflection : the angle that a ray of light takes as it is reflected off a surface.
Photons : units of electromagnetic energy that act like both particles and waves.
