Show Answer Key & Explanations
Step-by-step solution for: Waves online worksheet
Let me work through each question step by step.
Question 1: Which statement accurately describes the two waves below?
Looking at the two wave diagrams:
- Left wave: Has more cycles/waves in the same space (higher frequency, shorter wavelength)
- Right wave: Has fewer cycles/waves in the same space (lower frequency, longer wavelength)
Both waves appear to have the same amplitude (height from center line to peak).
The accurate description would be: The left wave has a higher frequency and shorter wavelength than the right wave.
Question 2: Which wave is carrying the most energy?
Looking at the three waves with different amplitudes:
- Low amplitude wave
- Medium amplitude wave
- High amplitude wave
Energy in a wave is related to both amplitude AND frequency. However, when comparing waves of the SAME frequency (which these appear to be - they have the same number of cycles), the wave with the HIGHEST AMPLITUDE carries the most energy.
Answer: The high amplitude wave carries the most energy.
Question 3: What happens to the wavelength of a wave as frequency increases?
From the electromagnetic spectrum diagram at the top:
- Moving left to right: wavelength INCREASES (0.0001 nm → 100 m)
- Moving left to right: energy DECREASES
- Frequency is inversely related to wavelength
When frequency INCREASES, wavelength DECREASES.
When frequency DECREASES, wavelength INCREASES.
Answer: As frequency increases, wavelength decreases.
Question 4: What two factors cause waves to carry more energy?
Based on wave physics and the diagram:
1. Amplitude - Higher amplitude = more energy
2. Frequency - Higher frequency = more energy
These are the two key factors that determine wave energy.
Question 5: Fill in the blanks
Let me work through this systematically:
"On the electromagnetic spectrum as the wavelength decreases, frequency __________."
- When wavelength decreases, frequency INCREASES (they're inversely related)
"As the wavelength __________, frequency decreases."
- When wavelength INCREASES, frequency decreases
"__________ and __________ determine the amount of energy a wave is carrying,"
- AMPLITUDE and FREQUENCY determine energy
"so the higher and shorter a wave is then the __________ the amplitude and the __________ the frequency."
- "Higher" refers to amplitude, so: GREATER/HIGHER the amplitude
- "Shorter" refers to wavelength, which means HIGHER frequency
- So: GREATER/HIGHER the amplitude and the HIGHER/GREATER the frequency
Wait, let me reconsider. "Higher and shorter a wave" - "higher" could mean taller amplitude, "shorter" means shorter wavelength (which equals higher frequency).
So: the GREATER/HIGHER the amplitude and the HIGHER/GREATER the frequency.
"As energy transfer decreases, the amplitude __________ causing a sound to get __________."
- As energy decreases, amplitude DECREASES
- This causes sound to get SOFTER/QUIETER
Let me verify my answers once more before finalizing...
All answers check out based on wave physics principles shown in the diagram.
