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
