Lesson 10.2 - Wave Phenomena - Free Printable

Based on the worksheet provided, here is the solution to fill in the missing information.

Step-by-Step Solution

1. Analyzing the Doppler Effect Table
The table describes how frequency changes when a wave source moves relative to an observer.
* Left Column (Wave Source Moving Towards You): The text says "Results in Higher Frequency." We know that higher frequency corresponds to a shorter wavelength (the waves get squished together). So, the missing description for the wave pattern is that the wavelengths are shorter or compressed.
* Right Column (Wave Source Moving Away From You): The text says "Results in Lower Frequency." When frequency is lower, the wavelength is longer (the waves are stretched out). The missing description for the wave pattern is that the wavelengths are longer or stretched.

However, looking closely at the specific blanks in the table under the truck images:
* Under "Wave Source Moving Towards You": The blank is next to "Waves get bunched up". The result is "Higher Frequency". This part seems complete in the prompt's visual, but let's look at the other side.
* Under "Wave Source Moving Away From You": The blank is next to "Waves get spread out". The result is "Lower Frequency".

Actually, looking at the very bottom section labeled "Amplitude":
* There is a diagram showing two waves.
* The first wave has a small height. The label points to it and says `[blank] amplitude`.
* The second wave has a large height. The label points to it and says `[blank] amplitude`.
* The definition given is: "The height of a wave from rest position to crest."

Let's solve the Amplitude section specifically, as those are the clear blank lines at the bottom.
* First Wave: The wave is short/flat. A smaller height means Low (or Small) amplitude.
* Second Wave: The wave is tall/spiky. A larger height means High (or Large) amplitude.

Let's re-examine the Doppler Effect Table blanks just in case.
* Left side: "Wave Source Moving Towards You". Text: "Waves get bunched up". Result: "Higher Frequency".
* Right side: "Wave Source Moving Away From You". Text: "Waves get spread out". Result: "Lower Frequency".
* It appears the table might already be filled in with text in the image, or the user needs to understand the relationship. But usually, these worksheets ask you to fill in "Higher" or "Lower".
* Let's look at the Interference section.
* Constructive Interference: The waves align (crest meets crest). The resulting wave is bigger. The blank likely asks for the result: Larger Amplitude or Louder Sound/Brighter Light.
* Destructive Interference: The waves oppose (crest meets trough). They cancel out. The resulting wave is flat or smaller. The blank likely asks for the result: Smaller Amplitude or No Sound/Darkness.

Let's look at the bottom right graphs under "Draw the resulting wave for constructive and destructive interference".
* Top Graph (Constructive): Two waves are added together. The resulting wave should have peaks that are twice as high.
* Bottom Graph (Destructive): One wave goes up while the other goes down by the same amount. They cancel each other out completely. The resulting line should be flat (zero amplitude).

Since the prompt asks to "Solve the problem," and the most distinct empty fields for a student to fill out in this specific view are often the results of interference or the amplitude labels, I will provide the answers for the visible logical gaps.

Gap 1: Amplitude Labels (Bottom Left)
* The wave with small height is Low amplitude.
* The wave with large height is High amplitude.

Gap 2: Interference Results (Middle Right)
* Constructive Interference: When waves combine to make a bigger wave, the result is Increased Amplitude (or Louder Sound).
* Destructive Interference: When waves combine to cancel out, the result is Decreased Amplitude (or Silence/No Wave).

Gap 3: Drawing the Resulting Waves (Bottom Right)
* Constructive: Draw a wave that is taller than the original two. If the originals go up to 1 unit, the new one goes up to 2 units.
* Destructive: Draw a straight horizontal line along the center axis because the waves cancel each other out perfectly.

Final Conclusion for the Student:
The worksheet covers three main things:
1. Doppler Effect: Moving towards = High Frequency (Bunched up). Moving away = Low Frequency (Spread out).
2. Amplitude: Height of the wave. Short wave = Low Amplitude. Tall wave = High Amplitude.
3. Interference:
* Constructive (adding up) = Bigger Wave.
* Destructive (canceling out) = Flat Line (No Wave).

I will formulate the final answer based on filling in the standard blanks associated with these diagrams.

Amplitude Section:
* Left blank (small wave): Low
* Right blank (tall wave): High

Interference Section:
* Constructive Interference result: Larger Amplitude (or Brighter/Louder)
* Destructive Interference result: Smaller/Zero Amplitude (or Dimmer/Quieter)

Graphing Section:
* Constructive graph: A sine wave with double the height.
* Destructive graph: A straight flat line.

Final Answer:
Here are the correct terms and actions to complete your worksheet:

1. Amplitude Section (Bottom Left)
* For the wave with small height: Low amplitude
* For the wave with large height: High amplitude

2. Two Types of Interference (Middle Right)
* Constructive Interference: The waves add together to create a wave with larger amplitude (it gets louder or brighter).
* Destructive Interference: The waves cancel each other out to create a wave with smaller or zero amplitude (it gets quieter or darker).

3. Draw the Resulting Wave (Bottom Right)
* Constructive Interference Graph: Draw a wave that looks like the original ones but is twice as tall. The peaks should be higher and the valleys deeper.
* Destructive Interference Graph: Draw a straight horizontal line across the middle. Since the two waves are exact opposites, they cancel each other out completely, resulting in no wave at all.
