Tabula Rosy's Learning Lab Trivia Quiz

Answer: Acoustics

The science of the production, transmission and capture of the effects of sound is called acoustics. The pitch of sound can be measured in wavelengths. High-frequency (short-wavelength) sound waves are known as overtones. If a sound is higher frequency than can be heard in human hearing it is called ultrasound, or ultrasonic waves.

Some uses of ultrasonic waves are in motion detection and prenatal imaging.

Answer: Amorphous

The atoms and the molecules of a solid can be amorphous or crystalline.
An amorphous structure, almost always, is basically a random structure. Many a physics textbook will have as an example that an amorphous solid does not have a lattice-like pattern of atoms and molecules. A crystalline form of the atoms of a solid has a more orderly structure.
The word amorphous comes from the Greek meaning having no shape.

Answer: Buoyant force

Buoyant force is the name for the process that makes an object immersed in a fluid rise to the top of a container. Examples of buoyant force at work are ice cubes floating to the top in your gin and tonic glass or taking your favorite float with a cup holder and a book into your swimming pool. Due to buoyant force you will float atop the water, read, and not spill your drink.

Answer: Dioptre

The unit of optical power of a lens is called a dioptre. The numbers on your prescription eye glasses represent the number of dioptres needed to improve your eyesight. Dioptres are abbreviated by the letter, "D". If your measured dioptre is -1.00 then you are short one dioptre indicating you may in time need reading glasses. "D" +1.00 indicates you are +1.00 dioptre indicating a minor distance vision problem. All the incorrect answers are figments of my imagination.

Answer: By an absence of light behind the object

When light hits an object, it creates an absence of light behind it and that darkness on the side opposite the light source is what we call a shadow. Shadows can have color if the light is passing through a translucent object such as light passing through a stained glass window.

This occurs when some of the light is not blocked. Have you ever been in a room with stained glass windows and marveled at the colored shadows of the light reflected on the wall or ceiling? I love to see them in a church.

Answer: Nucleon

Nucleon is a generic term for the proton and/or neutron which can make up the nucleus of an atom together. Protons are positively charged particles and neutrons are neutral particles. Scientists are working on proton therapy as an aid in defeating cancer. Proton therapy is said to be a number one treatment in prostate cancer.

It is sometimes used in the treatment of lung and liver cancer also.

Answer: Cable TV

Optical fibers are long thin threads of glass-like fibers, thinner than a human hair, used to transmit light based on total internal reflection. Optical fibers are used in cable TV, satellite TV, and long distance signal transmission.

Answer: Hooke's Law

Hooke's Law is a mathematical formula to explain how a spring works.

A Slinky toy, which is a series of connected coiled rings, is an example of Hooke's Law. Without giving the math formula, Hooke's law shows how a spring can oscillate or have damped oscillation. Using the toy "Slinky" as an example, we know that it prefers to stay in one coiled length, but if you pull or compress it, it will oscillate (move in one direction and back again until it returns to its original state). Damped oscillation occurs when the object eventually tires (often due to friction) and comes to rest in its original state.

Answer: Light Amplification through Stimulated Emission of Radiation

"LASER" is an acronym for Light Amplification through Stimulated Emission of Radiation. The dictionary definition of a laser is a tool that creates a strong light beam, and is made of atoms and molecules in an excited energy state. In May of 1960 at The Hughes Research Labs in Malibu California, through the efforts of Theodore Maiman, the first working laser was demonstrated. Laser procedures in medicine can improve vision, aid in removing skin conditions, remove unwanted hair, and for those Mommies who may want this, to remove stretch marks. Thanks to the site Your Dictionary for the simple definition making sense of all the longer explanations I had read.

Answer: Doxology

The correct answer that does not belong with the others is Doxology, which in the Christian religion is a hymn of praise to God that is sometimes chanted or sung. All of the wrong answers listed above do integrate with the science of Physics but each has a distinction which separates them from physics.

When you study chemistry you study matter and how it interacts with a concentration on elements and molecules. The study of biology is learning about living things, with a concentration on plants and animals and how they operate in their environments. Astronomy is the study of the stars, planets, and all that constitutes our universe. Astronomy is said to be the oldest science.
