What part of a wave measures how tall or short it is?

Amplitude

100

What is the definition of frequency?

How many waves pass a point in one second

100

What is wavelength?

The distance from one crest to the next crest

100

What happens when light bounces off a surface?

Reflection

100

What does energy do in a wave?

It moves or transfers through matter or space

200

If a wave’s amplitude increases, what happens to the energy?

Increases

200

A wave with high frequency has waves that are (close together / far apart)?

Close together

200

If the wavelength gets longer, what happens to the frequency?

it decreases

200

What object is a common example of reflection?

mirrors

200

If amplitude increases, what happens to the wave’s energy?

Energy increases

300

A wave with a small amplitude will carry (more / less) energy.

less

300

If you increase frequency, what happens to the wavelength?

It gets shorter

300

Which has a shorter wavelength: blue light or red light?

blue

300

What is the angle between the incoming and outgoing light called?

Angle of incidence and angle of reflection

300

Which has more energy — a light wave or a sound wave?

A light wave

400

What does amplitude tell us about a sound wave?

The loudness (volume)

400

What kind of sound has a higher frequency — a whistle or a drum?

A whistle

400

How does wavelength affect the color of light we see?

Different wavelengths make different colors

400

What happens to light waves when they hit a smooth surface vs. a rough surface?

Smooth = clear reflection, Rough = scattered reflection

400

Why does ultraviolet light have more energy than visible light?

It has a shorter wavelength and higher frequency

500

How could you show higher amplitude in a jump rope wave?

Move your hand up and down with greater force or height

500

How is frequency related to energy?

Higher frequency = higher energy

500

How can you measure wavelength on a wave graph?

Measure the distance between two matching points (crest to crest or trough to trough)

500

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

500

How can you tell a wave has high energy by looking at a graph?

It has high amplitude and closely spaced waves (high frequency)
