Sound and light energy
New Hampshire College and Career Ready Education Standards. Sound is a type of energy that travels in waves which are caused by vibrations. Characteristics of Sound. Vibrations: movements made rapidly back and forth. Sound Waves: an invisible transfer of sound energy as it travels away from the energy source. Wavelength: the distance between a point on one sound wave and a similar point on another sound wave. Frequency: The number of vibrations in a period of time is called the frequency of a vibration. Volume: The loudness or quietness of a sound is its volume. Read More...

NH.PS2. Physical Science: Energy is necessary for change to occur in matter. Energy can be stored, transferred and transformed, but cannot be destroyed.
S:PS2:6:3.1. Energy: Students will explain that the pitch of a sound is dependent on the frequency of the vibration producing it.
S:PS2:6:3.2. Energy: Students will explain that sound vibrations move at different speeds, have different wavelengths; and establish wave-like disturbances that emanate from the source.
