Wave Nature of Light and the Two Point interference
When two opposite ideas exist at the same time. We call that:
Duality
True or False: The transmission axis is the axis in which light is absorbed. The Polarized light is perpendicular to this axis.
False
Radio waves have (low/ high) energy and frequency, and (large/ small) wavelength.
Low, Large
Red, green, and blue
The pigment cyan absorbs what primary color?
Red
What are three wave behavior does light exhibit?
Diffraction
Interference
Polarization
True or False: The alignment of a filter's molecules is the axis in which light is absorbed. The Polarized light is perpendicular to this axis.
True
Gamma waves have (low/ high) energy and frequency, and (large/ small) wavelength.
High/ small
When adding or subtracting colors. What colors from incident light are absorbed in an apple?
Blue and green
If a t-shirt is pigmented with magenta and yellow, what color will be reflected with incident white light?
Red
Light behaves like particles in _____ circumstances. Light behaves like a wave in _____ circumstances.
Macroscopic, Microscopic
Light passes through two horizontal polaroid filters. What direction is the light vibrating? What is the intensity of the light after the filters compared to before filters?
Perpendicular
1/2 the original intensity
What kind of waves are large enough to diffract around houses?
Radio waves
When adding or subtracting colors. What model should one use in order to accurately calculate what color an object reflects?
Incident-Absorbed-Reflected model
If a t-shirt is pigmented with cyan and yellow, what color will be reflected with incident white light?
When referring to interference: Peaks with peaks and troughs with troughs end in what kind of interference?
Constructive interference.
Light passes through horizontal and vertical polaroid filters. What direction is the light vibrating? What is the intensity of the light after the filters compared to before filters?
No light passes through.
What section in the electromagnetic spectrum holds the smallest portion of the spectrum.
The visible light spectrum.
If all three primary colors (RGB) are used in incident light. The light is what color?
White
An article of clothing has no pigmentation added to it. What color is observed in incident white light?
White
When referring to interference: Peaks with troughs and troughs with peaks have what kind of interference?
Destructive interference
When out on a lake or driving a car, you tend to get an annoying glare that can hurt your eyes. But with polaroid filtered sunglasses you can blot out the glare!
What direction does the axis of transmission need to be in order to block the partially polarized light?
Vertical
True or false: The color red has a greater wavelength than the color violet.
When it comes to humans observing light. What 3 factors come into play?
Physics, physiology, psychology.
An article of clothing is pigmented with cyan, magenta, and yellow. What color will be observed when shown in incident white light?
Black
