7 Questions
What is the difference between cerebral achromatopsia and congenital achromatopsia?
Cerebral achromatopsia is a genetic absence of one or more cone receptors, while congenital achromatopsia is caused by damage to the cerebral cortex.
What are the aesthetic and signaling functions of color perception?
Identifying and classifying objects and aposematism.
What did Newton's experiment show about white light?
That every wavelength is a constituent of white light.
What range of wavelengths are visible to humans?
400nm to 700nm
What is spectral power distribution?
The distribution of light energy across different wavelengths.
What causes chromatic colors to occur?
When some wavelengths are reflected more than others.
What does selective transmission mean?
That only some wavelengths pass through an object or substance
Study Notes
- Cerebral achromatopsia is caused by damage to the cerebral cortex, while congenital achromatopsia is a genetic absence of one or more cone receptors.
- Color perception has aesthetic and signaling functions, such as identifying and classifying objects and aposematism.
- Color can also cue emotions in facial expressions.
- Newton's experiment showed that every wavelength is a constituent of white light.
- Visible wavelengths range from 400nm to 700nm in the electromagnetic spectrum.
- Spectral power distribution is highest at different wavelengths for different types of light.
- Most forms of light are heterochromatic mixtures of light frequencies.
- Chromatic colors occur when some wavelengths are reflected more than others, while achromatic colors occur when light is reflected equally across the spectrum.
- Selective transmission means that only some wavelengths pass through an object or substance.
- Monochromatic light has the highest intensity at the wavelength it is set to.
