Waves Basics

1. In the wave diagram shown, what part of a wave is represented by A?

• wavelength
• frequency
• amplitude
• crest
• trough

2. In the wave diagram shown, what part of a wave is represented by B?

• wavelength
• frequency
• amplitude
• crest
• trough

3. In the wave diagram shown, what part of a wave is represented by C?

• wavelength
• frequency
• amplitude
• crest
• trough

4. In the wave diagram shown, what part of a wave is represented by D?

• wavelength
• frequency
• amplitude

• trough

5. What is the definition of wavelength?

• the height of the wave from the crest to the trough
• the number of waves that pass by each second
• the distance from one crest to the next crest
• the height of the wave from crest to middle (or rest) position

6. What is the definition of amplitude?

• the height of the wave from the crest to the trough
• the number of waves that pass by each second
• the distance from one crest to the next crest
• the height of the wave from crest to middle (or rest) position

7. What is the definition of frequency?

• the height of the wave from the crest to the trough
• the number of waves that pass by each second
• the distance from one crest to the next crest
• the height of the wave from crest to middle (or rest) position

8. Which wave has a shorter wavelength?

• Blue (top)
• Red (bottom)
• They both have the same wavelength.

9. Which wave has a higher frequency?

• Blue (top)
• Red (bottom)
• They both have the same frequency.

10. Which wave has a larger amplitude?

• Blue (top)
• Red (bottom)
• They both have the same amplitude.
