P6 Waves Flashcards
Frequency: definition, symbol, measurement
The amount of waves that pass a point every second
Symbol: f
Measurement: Hz
Wavelength: definition, symbol, measurement
The distance between two peaks of a wave
Symbol: λ
Measurement: m
Wave speed: definition, symbol, measurement
The speed at which the wave travels
Symbol: v
Measurement: m/s
Period: definition, symbol, measurement
The time it takes for one wave to pass a point
Symbol: T
Measurement: s
Wave speed calculations
distance / time
f x λ
What is a transverse wave?
A wave where the oscillations are perpendicular to the direction of energy transfer
What is a longitudinal wave?
A wave where the oscillations are parallel to the direction of energy transfer
What type of wave is a sound wave?
Longitudinal
What type of wave are all electromagnetic waves?
Transverse
Electromagnetic spectrum
Radio Microwaves Infrared Visible light Ultraviolet X-rays Gamma
Trends across the electromagnetic spectrum (going up)
Wavelength decreases
Frequency increases
Speed does not change
What is a mechanical wave?
A wave that requires matter in order to travel
Two examples of a mechanical wave:
Sound wave
Water wave
Frequency calculation:
