Open Ended

How are you feeling today?

(Please use complete sentences when writing)

Ex: "I feel great today. I am winning today!"

Multiple Choice

Compression

• Compression is the region in a wave where particles are farthest apart.
• Compression refers to the speed of the wave.
• Compression is the region in a wave where particles are closest together.
• Compression is only present in sound waves, not other types of waves.

Multiple Choice

Rarefactions

• Rarefactions are regions in a wave where particles are compressed, leading to an increase in pressure.
• Rarefactions are regions in a wave where particles are spread out, leading to a decrease in pressure.

Draw

Circle the less dense regions.

Draw

Circle a compression region.

Multiple Choice

Crest

• Highest point of the wave where it breaks and forms white foam
• Middle of the wave where it is calm
• Lowest point of the wave
• The point where the wave starts

Multiple Choice

Trough

• The trough in a wave is a musical instrument used by sailors.
• The trough in a wave is a type of bird that flies over the ocean.
• The trough in a wave is the lowest point between two crests.
• The trough in a wave is the highest point between two crests.

Open Ended

Multiple Choice

What is wavelength?

• Wavelength is the distance between two consecutive points of a wave that are in phase.
• Wavelength is the amplitude of a wave.
• Wavelength is the speed of light in a vacuum.
• Wavelength is the time it takes for a wave to complete one cycle.

Multiple Choice

What unit is used to measure wavelength?

• meters (m) or nanometers (nm)
• liters (L)
• inches (in)
• grams (g)

Multiple Choice

How is wavelength measured in a transverse wave?

• By measuring the amplitude of the wave
• By counting the number of oscillations per second
• By measuring the distance between two consecutive points on the wave that are in phase with each other, such as two crests or two troughs.

• By observing the color of the wave

Multiple Choice

How is wavelength measured in a longitudinal wave?

• By measuring the distance between two consecutive compressions or rarefactions in the wave.
• By counting the number of particles in the wave
• By measuring the wave's frequency
• By analyzing the wave's color
