Definitions

Types of Waves

(1) Reflection or (2) refraction A B 2 1 E C D 2 1 1

1) Reflection 2) refraction 3) diffraction A 2 C D B 3 2 1

1) Reflection 2) refraction 3) diffraction 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. 1 d. 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 1 4) These waves are the ones that give us sunburn. 2 5) These wavelengths are the colors of the spectrum. 1

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. 3 3. When a wave bounces off a shiny surface. 1 4. The release of light energy by particles of matter that has absorbed the energy. 3 5. Angle of incidence = angle of reflection 1

LENSES 1) Concave or 2) Convex 1) Telescope-2 2) Microscope-1 3) A peephole in your front door-1

Lenses: 1) Concave or 2) Convex 1 2

Mirror: 1) Concave 2) Convex 2 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!

A. liquid B. solid 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? Frequency = pitch!!!!! Higher because more frequency

Which Wave Interaction 1) Diffraction 2 2) Reflection 3 3) Refraction 1.

Doppler Effect • Doppler Effect – change in wave frequency caused by a moving wave source w moving toward you pitch sounds higher w moving away from you pitch sounds lower
