Waves In A Tank Paper2 Flashcards
What is the purpose of the practical on waves in a tank?
To find out how wavelength, frequency, and wave speed are related.
What happens to the wavelength if you double the frequency?
The wavelength is halved.
What remains constant in the wave speed calculations?
Wave speed stays the same because it’s always the same material (string).
What apparatus is used to produce waves in the practical?
Oscillating paddle.
What is one reason why calculated wave speeds are not identical?
It’s hard to be 100% accurate with measurements each time.
What are some factors that can affect measurement accuracy in the practical?
Reflected waves, visibility of waves, and movement of waves.
How could you improve the accuracy of wave measurements?
Add insulation to stop reflected waves, use a bigger pool, brighter light, sharper paddle.
What concepts might students be asked to comment on regarding the practical?
Repeatability, reproducibility, range, uncertainty, and calculating means.
Fill in the blank: Wave speed is the same in water, but it is hard to be _______ with measurements.
100% accurate
True or False: Wave patterns can be displayed on a viewing screen.
True
