Wave Properties ม5

What do all waves have in common?

• They transfer matter.
• All waves travel at the same speed.
• They transfer energy.
• They transfer electricity.

Which of the following is ALWAYS true?

• The greater the frequency, the faster the wave speed

• The greater the wave speed, the larger the wavelength

• When the wave speed is constant, increasing the frequency decreases the wavelength

• When the wave speed is constant, increasing the frequency increases the wavelength

The number of waves that pass somewhere in a second is:

• amplitude

• frequency

• wavelength

• period

#1 refers to the

A period is

• Amount of time it takes a wavelength to complete one cycle.
• How many wave lengths happen in a second.
• An indication of the amount of energy in a wave.
• The distance between two crests or two troughs.
