Define amplitude, frequency, period, wavelength, and velocity of a wave; Relate wave frequency, period, wavelength, and velocity; Solve problems involving wave properties
1. Draw a picture of a wave and label wavelength and amplitude. What is a wave? A wave is simply energy moving from one place to another. It always needs something to move through. Example: Sound is the wave and the air is the medium. Wave Anatomy. Crest. Wavelength = : : ( ) Trough. In Phase. Amplitude. = : : ( ) Period.

4 Δεκ 2023 · Students learn about the types of waves and how they change direction, as well as basic wave properties such as wavelength, frequency, amplitude and speed. During the presentation of lecture information on wave characteristics and properties, students take notes using a handout.
A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave. A wave’s frequency can be measured by how many crests (or how many troughs) pass a location in a certain amount of time.
Adjust frequency and amplitude, and observe the effects. Hear the sound produced by the speaker, and discover what determines the color of light. Make waves with a dripping faucet, audio speaker, or laser!
Frequency tells us how many waves are passing a point per second, the inverse of time. Wavelength tells us the length of those waves in metres, almost like a displacement. If we multiply these two together, we are really multiplying 1/s and m … which gives us m/s, the velocity of the wave!
