Wave or Particle?
This type of wave does not require a medium to travel.
What is an electromagnetic wave?
This acronym helps remember the visible light spectrum from longest to shortest wavelength.
What is ROY G. BIV?
When light bounces off a mirror, it undergoes this process.
What is reflection?
The bending of light as it passes from one transparent medium to another.
What is refraction?
Objects appear a certain color because they reflect specific __________ of light.
What are wavelengths?
All forms of electromagnetic waves travel at this universal speed in a vacuum.
What is the speed of light (c)?
In visible light, this color has the longest wavelength.
What is red?
The incoming beam of light striking a surface is called this.
What is the incident beam?
This boundary between two materials is where reflection and refraction occur.
What is an interface?
This type of surface absorbs more light: white or black?
What is black?
Light can behave both as a wave and as these single, massless packets of energy.
What are photons?
This color has the shortest wavelength in the visible spectrum.
What is violet?
This angle is formed between the incoming beam and a line perpendicular to the surface.
What is the angle of incidence?
When light enters a new medium, its frequency stays constant but this property changes.
What is wavelength?
When light is absorbed, it is typically transformed into this type of energy.
What is heat (thermal energy)?
This property of electromagnetic waves determines whether they are radio waves, visible light, or gamma rays.
What is frequency?
On the electromagnetic spectrum, these waves have shorter wavelengths and higher frequencies than ultraviolet light.
What are X-rays or gamma rays?
Light always travels in this manner unless it interacts with matter.
What is in a straight line?
When light bends so much that it cannot exit the medium, this phenomenon occurs.
What is total internal reflection?
A red filter placed over green light results in this outcome.
What is little to no light passes through / it appears very dark?
Experimental evidence showing that light behaves as photons rather than purely as a classical wave.
What is the photoelectric effect?
A device used in class to separate light into its component wavelengths.
What is a spectroscope?
This relationship describes how the angle of incidence compares to the angle of reflection.
What is they are equal?
Light refracts when entering a new medium because its ______ changes.
What is speed?
We cannot see color in the dark because there is no light to do this.
What is reflect off objects and enter our eyes?
