FLASHCARD QUESTION
Front
What is the definition of wavelength?
Back
Wavelength is the distance between two consecutive points that are in phase on a wave, such as from crest to crest or trough to trough.
2.
FLASHCARD QUESTION
Front
True or False: Wavelength is the distance from rest to the highest or lowest point.
Back
False

FLASHCARD QUESTION
Front
What is amplitude in the context of waves?
Back
Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.
4.
FLASHCARD QUESTION
Front
True or False: Amplitude and wavelength are the same.
Back
False
5.
FLASHCARD QUESTION
Front
What does the crest of a wave represent?
Back
The crest is the highest point of a wave.

FLASHCARD QUESTION
Front
If five waves pass a point in 37 seconds, how do you calculate frequency?
Back
Frequency (f) is calculated as the number of waves (n) divided by the time (t) in seconds: f = n/t. In this case, f = 5/37 = 0.135 Hz.

FLASHCARD QUESTION
Front
What is the formula for calculating wave speed?
Back
Wave speed (v) is calculated using the formula v = frequency (f) × wavelength (λ).
