Which wave has the highest frequency?

• 1
• 2
• 3
• 4

Frequency is

• Amount of time it takes for one wavelength
• How many wavelengths are completed in one second
• Distance between two crests or two troughs
• Amount of energy in a wave

Frequency is measured in

• Newtons
• Joules
• Hertz
• Decibels

Which is the correct equation for calculating the speed of a wave?

• T = 1/f
• Speed= Wavelength x Period
• Speed = Wavelength/Frequency
• Speed= Wavelength x Frequency

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.
