Properties of Waves
Grade 4 · Science · Waves and Information · Oklahoma, USA
Lesson Summary
Waves have measurable properties like wavelength, amplitude, and frequency.
Explanation
Wavelength is the distance from one wave peak to the next. Amplitude is the height of the wave from the middle to the top; bigger amplitude means more energy. Frequency is how many waves pass a point in one second and is measured in hertz. High-frequency waves are close together; low-frequency waves are spread apart. These properties help scientists describe and compare different kinds of waves.
Practice Questions
