Matching: You may need to minimize the screen (ctrl -) to see them all Speed of Sound Varies but at sea level it is 1190 km Longitudinal Type of wave sound travels in Amplitude Determines loudness of a sound Doppler Effect Apparent change in the length of a wave sound due to the objects or observers position Frequency Determines the pitch of a sound wave Vibrations How sound waves travel Decibel Used to measure the intensity of a sound Ultrasonic above 20,000hz Infrasonic below 20hz Medium Needed for sound to travel Hertz how frequency is measured Fill in the parts of a sound wave Use the following terms: Source, wavelength, compression, rarefaction, rest Source Compression Rest Wavelength Rarefaction Fill in the blanks Sound waves are caused by vibrations. Sound travels as longitudinal waves. Frequency is the number of complete waves that pass a point in a given amount of time. Frequency measures the pitch of a sound. The height of a waves is called its amplitude. This measures the loudness of a sound. Sound travel slow at low temperatures and moves fastest through solids. Draw It!
