Waves In A Solid Paper2

Question 1

What is the main objective of the practical experiment on waves in a solid?

Answer 1

To find out how wavelength, frequency and wave speed are related

Understanding these relationships is crucial for studying wave behavior in different materials.

Question 2

If the frequency is doubled, what happens to the wavelength?

Answer 2

The wavelength is halved

This illustrates the inverse relationship between frequency and wavelength.

Question 3

How does wave speed change when the material remains the same?

Answer 3

Wave speed stays the same

This is true as long as the wave is traveling through the same medium (e.g., string).

Question 4

What equipment is used to make the string vibrate and produce waves?

Answer 4

Frequency generator and vibrator (oscillator)

These devices are essential for creating controlled wave patterns in the experiment.

Question 5

What should you use to hold the string during the experiment?

Answer 5

Weight to hold the string tight (taut)

Keeping the string taut is important for accurate wave measurement.

Question 6

What might be a method to measure the waves more accurately?

Answer 6

Use a different colour or width string

This can enhance visibility and help in observing wave patterns more clearly.

Question 7

What concepts might be discussed related to the results of the experiment?

Answer 7

Repeatability, reproducibility, uncertainty, and calculating means

These concepts are important for evaluating the reliability and accuracy of experimental results.

Question 8

True or False: Doubling the frequency will increase the wave speed.

Answer 8

False

Wave speed remains constant when the material remains the same, regardless of changes in frequency or wavelength.
