Properties of Waves

What is the amplitude of a wave?

• The number of complete waves passing a point each second.
• The distance from a point on one wave to the same point on the adjacent wave.
• The time it takes for one complete wave to pass a point.
• The maxiumum displacement of a point on a wave from its undisturbed position.

What is the wavelength of a wave?

• The maxiumum displacement of a point on a wave from its undisturbed position.
• The time it takes for one complete wave to pass a point.
• The distance from a point on one wave to the same point on the adjacent wave.
• The number of complete waves passing a point each second.

What is the frequency of a wave?

• The maxiumum displacement of a point on a wave from its undisturbed position.
• The time it takes for one complete wave to pass a point.
• The distance from a point on one wave to the same point on the adjacent wave.
• The number of complete waves passing a point each second.

What is the period of a wave?

• The maxiumum displacement of a point on a wave from its undisturbed position.
• The distance from a point on one wave to the same point on the adjacent wave.

How can the wavelength of a longitudinal wave be found? Tick TWO that apply.

• By measuring one area of compression to the next area of rarefaction.
• By measuring one area of rarefaction to the next area of rarefaction.

The equation to calculate the period fo a wave is: T = 1/f What does T and f stand for and what are their units? Tick TWO.

• T = period - units are seconds, s
• f = frequency - units are herz, Hz
• T = time - units seconds, s
• f = wavelenghts - units lambda
