Wave Interactions: Light and Sound

Master wave interactions! Light, sound, EM spectrum, and more.

1.) Fill in the parts of the EM Spectrum.*It must look exactly like the word bank- watch out for capital letters* Infrared UV X-rays Radio Visible light Microwaves Gamma Radio Microwaves Infrared Visible light UV X-rays Gamma 2.) Which side of the electromagnetic (EM) spectrum has low wavelength, high frequency, and high energy? Left Right 3.) Which side of the electromagnetic (EM) spectrum has high wavelength, low frequency, and low energy? Left Right 4.) What type of waves make up the EMS? Transverse (Sound) Longitudinal (Light) Transverse (Light) Longitudinal (Sound) Label the waves image using the word bank terms exactly as they are shown (spelling counts). amplitude longitudinal transverse rarefaction wavelengthwavelength compression crest trough wavelength rarefaction compression wavelength trough amplitude crest longitudinal transverse 11.) Wave Interactions Match the correct wave interaction (reflection, refraction, and interference) with its definition. Occurs when a wave bounces off of an obstacle Reflection Occurs when a wave passes from one medium to another and changes direction. Refraction Occurs when two waves traveling in the same medium towards one another run into one another and either add their energies or cancel their energies Interference Type of interference that occurs when the crest of one wave meets up with the crest of another wave; they add their energies to make a higher amplitude wave Constructive interference Type of interference that occurs when the crest of one wave meets up with the trough of another wave; they subtract their energies to make a lower amplitude wave Destructive interference 12.) Fill in the blanks to the paragraph written below discussing sound. SOUNDis a type of energy that needs MATTER to travel. When sound energy moves matter, this is called VIBRATION. Sound waves are also called COMPRESSION OR LONGITUDINAL waves. COMPRESSIONS are the parts of the wave that are close together and RAREFACTIONS are the parts of the wave that are spread apart. Sound waves also bounce off and interact with surfaces. Some animals use ECHOLOCATION or the bouncing of sound waves off of matter to see where they are going. Scientists and military use SONAR underwater to learn about what is in the ocean.
