Waves - Equations Flashcards
How do you calculate the time period of a wave?
Remember -The period (T) is measured in seconds (s) The frequency (f) is measured in hertz (Hz)
Time period = 1
____________
frequency OR T = 1 \_\_\_\_\_\_\_\_ f
How do you calculate the speed of a wave?
Remember- wave speed (v) is measured in metres per
second (m/s)
frequency (f) is measured in Hertz (Hz)
wavelength (λ) is measured in metres (m)
wave speed = frequency × wavelength
OR v = f ʎ
How to calculate the speed of sound?
Remember- speed (v) is measured in metres per second
(m/s)
distance (s) is measured in metres (m)
time (t) is measured in seconds (s)
Speed = distance
________
time
OR v = d ------ t
