Waves
This is a repeating disturbance or vibration that transfers energy from one place to another.
This is the highest point of a transverse wave?
What is a crest?
This is when a wave bounces off a surface.
What is reflection?
This type of material allows light to pass through (e.g., clear glass).
What is transparent?
The symbol f represents this in the wave formula.
What is frequency?
This requires a medium to travel through.
What are mechanical waves?
This is the lowest point of a transverse wave.
What is a trough?
This is when a wave bends as it enters a new medium.
What is refraction?
This type of material scatters light (e.g., frosted glass).
What is translucent?
The symbol v represents this in the wave formula.
What is wave speed?
This is a wave that does not require a medium to travel through.
What are electromagnetic waves?
This is the distance between two consecutive crests or troughs.
What is a wavelength?
This is when energy is taken in by the material.
This type of material absorbs or reflects all light (e.g., wood).
What is opaque?
The symbol λ represents this in the wave formula.
What is wavelength?
This is a waves where the particles vibrate parallel to the direction of the wave.
What are longitudinal waves?
This is the number of complete wave cycles per second and is measured in hertz (Hz).
What is frequency?
This is when two waves overlap and interact.
What is interference?
Light waves are an example of this type of wave.
What are transverse or electromagnetic waves?
Challenge: This is the speed of a wave with a frequency of 500 Hz and a wavelength of 2 meters.
What is 1000 m/s
This is a wave where the particles vibrate perpendicular to the direction of the wave.
What is a transverse wave?
This is the maximum displacement of a wave from its rest position. When there is more of this, there is more energy.
What is amplitude?
This is when a wave spreads out after passing through an opening or around an obstacle.
What is diffraction?
Sound waves are an example of this type of wave.
What are mechanical or longitudinal waves.
Challenge: If a wave is traveling at 340 m/s and has a frequency of 170 Hz, this is its wavelength.
What is 2 meters?
