| I am the ability of sound to cause vibrations. | sound energy |
| I am rapid back and forth movements and I produce sound. | vibrations |
| I am a surge of sound energy that travels through matter. | sound wave |
| I determine the pitch of a sound. I am the number of times a sound vibrates in 1 second. | frequency |
| I am the distance between a point on 1 wave to the same point on the next wave. | wavelength |
| I am the process of making sound louder and I occur when the height of a sound wave increases. | amplification |
| I am the highness or lowness of a sound. I am determined by the frequency of sound waves. | pitch |
| I am the height of a sound wave. I determine the loudness of a sound. | amplitude |
| I am a unit used to measure the loudness of sound. | decibel |
| I am a combination of several different wavelengths of light traveling together. | white light |
| I am the band of light waves in the electromagnetic spectrum that vibrates at frequencies our eyes can detect. | visible spectrum |
| I am the ability of light to cause change, such as heating an object. | light energy |
