Mirror Magic
This type of mirror always produces a virtual image.
What is a convex mirror?
This type of lens always causes parallel light rays to bend away from the principal axis.
What is a diverging (or double concave) lens?
A negative image distance signifies that it is this.
What is virtual?
For a converging lens, a principal ray traveling parallel to the principal axis will refract through this specific point.
What is the focal point?
This physicist allegedly fell in love with a pigeon, was obsessed with the number 3, had photographic memory, and rarely slept.
Who is Nikola Tesla?
If you stand 2 meters in front of a flat, plane mirror, this is the total distance between you and your image.
What is 4 meters?
When an object is placed at 2F (twice the focal length) in front of a converging lens, the resulting real image will be located at this position on the other side.
What is 2F (or twice the focal length)?
What is negative?
For a thin lens, a principal ray passing directly through this point will not refract at all.
What is the center?
Hailed for discovering the first rules taught in physics, this man was so intensely anti-social that he hated talking to people. Studying optics, he once stuck a long packing needle into his own eye socket, poking around just to see how altering the shape of his eye would affect his vision.
Who is Sir Isaac Newton?
After a beam of light parallel to the principal axis hits a concave mirror, this is where it will reflect.
What is the focus?
If a converging lens produces a real image on a screen, this is what happens to the image if you cover the top half of the lens.
What is the image becomes dimmer?
On the AP test and Holloway’s tests, images must be described using at least three of these six adjectives.
What are virtual, real, inverted, upright, reduced, and enlarged?
These are the three rules Holloway teaches us for drawing a ray diagram for a mirror.
Parallel to focus, center to center, focus to parallel.
This global celebrity loved sailing but was notoriously terrible at it, frequently capsizing his boat and requiring coast guards to rescue him because he never learned to swim. After his death, his brain was stolen by a Princeton pathologist and eventually studied by researchers, who revealed that his brain lacked a specific fold, allowing his parietal lobes to be 15% wider than average. Theoretically, this gave him enhanced mathematical and spacial abilities.
Who is Albert Einstein?
An object is placed 15 cm in front of a concave mirror with a radius of curvature of 20 cm. This is the image distance.
What is +30 cm?
This type of lens is used to correct myopia.
What is a diverging (or double concave) lens?
For lenses, a positive image distance means the image is located on this side of the lens relative to the object.
What is the opposite side?
The rules for drawing a lens ray diagram versus a mirror ray diagram differ since lens ray diagrams replace one similar-sounding rule with this.
What is FALSE focus to parallel?
This French physicist never went to school — he educated himself using his father’s extensive library and taught himself Latin in a few weeks at age 12. He was known to despise doing physical experiments, as ‘mathematics told him what was possible.’
Who is André-Marie Ampère?
A freshman looks into a makeup mirror and sees an upright, magnified view of their face. This describes the nature of the image and the location of their face relative to the mirror’s focal length (2 answers).
What is a virtual image and closer than the focal length?
A converging lens with focal length of 10 cm forms an upright image 3 times the size of the object. This is the object distance.
What is 6.67 cm?
A real object is placed in front of a curved mirror. If the resulting magnification is M = - 0.5 and the object distance is 40 cm, this is the focal length of the mirror.
What is +13.3 cm?
[Real world issues] These are responsible for imperfect images formed by lenses and mirrors.
What are abberations?
Known for discoveries within modern physics but born into French nobility, this physicist was actually a prince and eventually a duke of France.
