Waves, Sound and Light

Wave your hands in the air like you just don’t care

100

The distance between the crest and the resting point of a wave is____

Amplitude

200

When the motion of the medium is perpendicular to the direction of the energy of the wave_____

transverse

300

When wavelength decreases then frequency_____

Increases

400

_____ waves transfer energy through empty space

EM

500

Any substance that a wave moves through_____

A medium

Less is more (less wavelength=more frequency)

100

Type of wave used to transmit cell phone signals

Microwaves

200

Visible white light contains?

All colors in the rainbow 

300

Joseph's shirt looks red because?

His shirt is reflecting red and absorbing every other color. (molecules in the shirt vibrate at frequencies that resonate with all colors but red so it is reflected)

400

Radio and TV transmission use?

Radio waves

500

To kill germs and sterilize science goggles, we use?

Ultra violet waves OR Gamma waves

Waveriffic

100

When light travels through a medium and changes speed, it bends.  This is _____________

Refraction 

200

Sound typically travels fastest through a solid because ___________________

The molecules in a solid are closer together or more dense.

300

Sound waves are caused by the vibration of molecules.  These molecules move in the same direction as the energy of the wave.  This type of wave is called _______________________.

longitudinal

400

These 2 parts of a wave indicate it's energy levels.

Frequency and Amplitude

500

This part of a wave indicates how loud a sound is.

Amplitude

Light it Up

100

This states that the angle of incidence = the angle of reflection.

Law of Reflection.

200

When all light is absorbed, this is the color we see.

Black

300

When all light is reflected, this is the color that we see.

White

400

This happens to the colors within white light that are not seen after they hit a substance.

Absorption

500

Which part of the EM spectrum travels at the speed of light?

All of them.  (They are all types of light, we just can't see most of them.)
