Matter of the day:

X-Ray Radiography (Photos)

Formula/Diagram

What is it?:

An X-ray beam is shot through a body part. X-rays pass through muscle & flesh, but are absorbed more by bone and other things. Bone shows up white on the film.

Why does it matter?.

Lets us see broken bones, pneumonia, stones, and some cancers.

Vocabulary:

electromagnetic wave: is a transverse wave that transfers electrical and magnetic energy.

E-M waves do not need a medium (something to go through.)

electromagnetic radiation: energy that is transfered through space by electromagnetic waves.

speed of E-M waves (aka Speed of Light): 300,000 km/second in a vacuum. (slower in mediums.)

Matter of the day:

  • Visible Light Spectrum

Diagram:

What is it?:

  • We see different frequencies of light waves as the colors of the rainbow.

Why it matters

  • Combinations of colors can be added (lights) or subtracted (filters) to make new colors.

Matter of the day:

Tuning Fork

Made Of:

Metals: Brass, steel, or aluminum

What is it?:A device that converts an impulse (hit) into compressed sound waves by vibrating back and forth.

Its pitch depends on the length of the fork, its area accross, and its density.

It is in a fork shape so that it creates a pure tone & the base moves up and down.

Why it matters

It is used to tune instruments and in our experiments.

_____________________________________________________________

Vocabulary:

Sound wave: a longitudinal wave in a medium carries energy.

density: mass in a given volume.

In fluids like air, the medium compresses and then expands (rarefies) as the wave passes.

Compressions are more dense, rarefactions, less dense.

diffraction: sound waves spread out after passing through a small openning.

elasticity: a property of materials that bend back after a wave passes.
