Waves Flashcards
Period Equation
Time/ # Cycles = S
What is the period?
The time a wave takes to complete a cycle
Frequency equation
Cycles / Time = I/ p or 1/ T in Hz
What is the frequency?
Number of cycles a wave makes in a single second
What is the relationship between period and frequency
Inversely proportional
What is the Amplitude (A)
the height between the centre and the peak
How do u find the centre of the wave
(trough + Crest) / 2
What is the wavelength ( λ)
The length of one cycle
What is the relationship between wavelength (λ) and frequency (f)?
Inversely proportional
What is the relationship between the period and wavelength (λ) ?
directly proportional
What is the relationship between energy and frequency (λ)?
Inversely proportional
What is the relationship between frequency and energy?
Directly proportional
What is the equation for wave speed
v = fλ
What does (v) equal to?
3 * 10^8
What is Energy equal to?
E= hf
what is plank’s constant?
6.626* 10^-34 J.S
What is electron volt equal to
1 ev = 1.602 * 10^-19
