1. Which one bends waves as it moves from one medium to another? 2

2. Which one is when waves move through the opening of a barrier? 3

3. Which one is when waves bounce off a barrier? 1

4. Which one is when waves bend around a barrier? 3

EM Spectrum

1) Radio waves 2) Microwaves 3) Infrared waves

a. These have shorter wavelengths than radio waves & can be used in satellite communication. 2

b. These waves have the highest frequency but shortest wavelength of the three listed above.3

c. These include television broadcasting waves.1d. These waves have the longest wavelengths but the

shortest frequency of ALL electromagnetic waves. 1

1) Visible light spectrum 2) Ultraviolet light 3) X-rays

4) Gamma Rays

1) These waves can penetrate solid objects and are used to diagnosis internal injuries. 3

2) These are the fastest waves but have the shortest wavelengths. 4

3) These wavelengths are those we can see 14) These waves are the ones that give us sunburn. 25) These wavelengths are the colors of the spectrum.

1) Reflection 2) Absorption 3) Scattering

1. When light waves slowly fade away because the energy is transferred to matter (usually a gas). 2

2. Fuzzy shadows. 33. When a wave bounces off a shiny surface. 14. The release of light energy by particles of

matter that has absorbed the energy. 35. Angle of incidence = angle of reflection 1

Sound Vocabulary

• Match definition to vocabulary• Sound : a) the matter through

which a wave travels• Vibration : b) a back and forth

movement• Longitudinal wave: c) the energy from

vibrating particles• Medium d) the method of

travel where particles vibrate back and forth

Sound waves require a medium. Circle the type of matter through which sound waves move the fastest?

FASTEST!

Assuming these are sound waves indicate which is moving through

1) Solid 2) Liquid 3) GasA B

C

B. solidA. liquid C. Gas

Which is the loudest?

Loudest, has a higher amplitude

Amplitude = loudness

Which is the loudest?

Loudest – higher amplitude

Which wave has the highest pitch?

Higher because more frequencyFrequency =

pitch!!!!!

Which Wave Interaction

1) Diffraction 2) Reflection 3) Refraction

23 1.

Doppler Effect

• Doppler Effect– change in wave frequency

caused by a moving wave source

moving toward you - pitch sounds higher

moving away from you - pitch sounds lower
