Describing Waves Flashcards
What are frequencies
the number of oscillations in a second
what is the equation for frequency
Frequency = 1/period
what is frequency measured in
frequency is measured in Hertz
what is the period of a wave
the period of a wave is the time taken to complete one oscillation
what is the equation for Period
Period = 1/frequency
what is the period of a wave measured in
the period of a wave is measured in seconds
what is the amplitude of a wave
the amplitude of a wave is the largest distance that a point on a wave length moved from its rest position
what is the wavelength
the wavelength is the distance between two adjacent wavefronts
What is defined as the greatest distance a point on the wave moves from its rest position?
The amplitude
A wave with a frequency of 6 kHz was found to oscillate 24,000 times. Over what time period was it measured?
4s
Calculate the speed of a water wave that has a wavelength of 2 m and a frequency of 3 Hz.
2m x 3Hz
what is the equation for speed
wave speed = frequency x wavelength
