Key Wave Properties
Before diving into the answers, let’s quickly summarize some essential wave properties that students should be familiar with:
| Property | Description |
|---|---|
| Wavelength | The distance between consecutive crests or troughs. |
| Frequency | The number of waves that pass a point in a second (Hz). |
| Amplitude | The maximum displacement of points on a wave from rest. |
| Speed | How fast the wave travels through a medium. |
Wave Worksheet 1: Questions and Answers
Now that we understand the importance of wave worksheets, let’s take a look at a hypothetical Wave Worksheet 1 and its answer key.
Question 1: Calculate the Frequency
If a wave has a speed of 300 m/s and a wavelength of 15 m, calculate the frequency.
Solution:
The formula to calculate frequency (f) is:
[ f = \frac{v}{\lambda} ]
Where:
- ( v ) = speed of the wave (300 m/s)
- ( \lambda ) = wavelength (15 m)
[ f = \frac{300}{15} = 20 , \text{Hz} ]
Question 2: Determine the Wavelength
A sound wave travels at a speed of 340 m/s and has a frequency of 170 Hz. Find the wavelength.
Solution:
Using the same formula:
[ \lambda = \frac{v}{f} ]
[ \lambda = \frac{340}{170} = 2 , \text{m} ]
Question 3: Find the Speed of the Wave
If the frequency of a wave is 50 Hz and the wavelength is 1.2 m, calculate its speed.
Solution:
Again using the wave speed formula:
[ v = f \times \lambda ]
[ v = 50 \times 1.2 = 60 , \text{m/s} ]
Question 4: What is the Amplitude?
In a wave, the maximum displacement from the rest position is 0.5 m. What is the amplitude?
Solution:
The amplitude is simply the maximum displacement, so:
Amplitude = 0.5 m
Question 5: Comparing Two Waves
Wave A has a frequency of 100 Hz and a speed of 200 m/s. Wave B has a frequency of 150 Hz. Which wave has a longer wavelength, and what is the value?
Solution:
-
Calculate the wavelength for Wave A: [ \lambda_A = \frac{v}{f} = \frac{200}{100} = 2 , \text{m} ]
-
For Wave B, first, we need to calculate its speed using the same formula: [ \lambda_B = \frac{v}{f} ]
Assuming Wave B travels at the same speed (for comparison):
[ \lambda_B = \frac{200}{150} \approx 1.33 , \text{m} ]
Conclusion: Wave A has a longer wavelength of 2 m compared to Wave B's approximately 1.33 m.
Important Note:
“Understanding wave properties is crucial not only for physics but also for various applications in technology and engineering. Mastering these fundamentals can lead to advanced studies and innovative solutions in the field.”
