What part of a wave measures how tall or short it is?
Amplitude
What is the definition of frequency?
How many waves pass a point in one second
What is wavelength?
The distance from one crest to the next crest
What happens when light bounces off a surface?
Reflection
What does energy do in a wave?
It moves or transfers through matter or space
If a wave’s amplitude increases, what happens to the energy?
Increases
A wave with high frequency has waves that are (close together / far apart)?
Close together
If the wavelength gets longer, what happens to the frequency?
it decreases
What object is a common example of reflection?
mirrors
If amplitude increases, what happens to the wave’s energy?
Energy increases
A wave with a small amplitude will carry (more / less) energy.
less
If you increase frequency, what happens to the wavelength?
It gets shorter
Which has a shorter wavelength: blue light or red light?
blue
What is the angle between the incoming and outgoing light called?
Angle of incidence and angle of reflection
Which has more energy — a light wave or a sound wave?
A light wave
What does amplitude tell us about a sound wave?
The loudness (volume)
What kind of sound has a higher frequency — a whistle or a drum?
A whistle
How does wavelength affect the color of light we see?
Different wavelengths make different colors
What happens to light waves when they hit a smooth surface vs. a rough surface?
Smooth = clear reflection, Rough = scattered reflection
Why does ultraviolet light have more energy than visible light?
It has a shorter wavelength and higher frequency
How could you show higher amplitude in a jump rope wave?
Move your hand up and down with greater force or height
How is frequency related to energy?
Higher frequency = higher energy
How can you measure wavelength on a wave graph?
Measure the distance between two matching points (crest to crest or trough to trough)
Why do you see your reflection in calm water but not in rough water?
Because calm water acts like a smooth mirror surface; rough water scatters light
How can you tell a wave has high energy by looking at a graph?
It has high amplitude and closely spaced waves (high frequency)
