Waves

Question 1

What is the difference between Longitudinal and Transverse waves?

Answer 1

The vibrations in a Longitudinal wave are parrelel to the direction the wave is travelling, while in a transverse wave they are perpendicular.

Question 2

What are the definitions of the following:

Amplitude

Wavefront

Frequency

Wavelength

Time Period

Answer 2

Amplitude- The Max disturbance caused by the wave. Measured from the highest point of the wave to the lowest

Wavefront- A line where all the waves are overlapping and are at the same point in the pattern and have the same difference

Frequency- The Number of waves per second produced by the source

Wavelength- The distance between a particular point on one wave and the next wave

Time Period- The time it takes to produce 1 wave

Question 3

Fill in the gaps

Waves transfer ______ and __________ without transferring ______

All waves can be ___________ and ___________

Answer 3

1. Energy
2. Information
3. Matter
4. Reflected
5. Refracted

Question 4

Equation for wave speed:

Answer 4

Wave Speed = Frequency x Wave Length

v = f x /|

Question 5

Equation for frequency and time period

Answer 5

Frequency = 1 / Time Period

F = 1/T
