Packet 3: Bonus 5

The thickness of these devices is usually assumed to be negligible when analyzing them with a ray transfer matrix. For 10 points each:
[10e] Name these devices whose focal length can often be approximated as half of their radius. These optical devices, which transmit and refract incoming light, come in convex and concave varieties.
ANSWER: lenses [accept thin lenses; accept convex lenses; accept concave lenses]
[10h] Images reflected in lenses may appear blurred at areas of high-contrast due to this phenomenon, in which light at different wavelengths have differing focal points.
ANSWER: chromatic aberration [prompt on aberration]
[10m] Chromatic aberration is caused by this phenomenon, which occurs when the index of refraction of the lens varies with the wavelength of the incoming light. This phenomenon causes white light to split as it’s passed through a prism.
ANSWER: optical dispersion [accept word forms]
