Properties of Waves
Grade 8 · Science · Energy and Waves · Nunavut, Canada
Lesson Summary
Learn the basic properties that describe all types of waves.
Explanation
A wave is a disturbance that transfers energy from one place to another without moving matter permanently. Key properties include wavelength (the distance between wave crests), frequency (how many waves pass a point per second), and amplitude (the height of the wave from rest position). Higher amplitude means more energy. Higher frequency means shorter wavelength. These properties apply to all waves, from ocean waves to sound to light.
Practice Questions
Q1: What is wavelength?
Answer: Wavelength is the distance between one wave crest and the next, or between any two identical points on consecutive waves.
Q2: If a wave has a high frequency, what happens to its wavelength?
Answer: The wavelength decreases. Frequency and wavelength are inversely related when wave speed is constant.
Q3: Two sound waves have the same frequency but different amplitudes. Which one is louder?
Answer: The one with the greater amplitude is louder, because amplitude determines the energy and volume of a sound wave.
