Card 1
Question: What is the relationship between wave speed (v), wavelength (λ), and frequency (f) of a traveling wave?
Answer: v = λ · f
Card 2
Question: What does the equation v = λ · f indicate about the relationship between frequency and wavelength if wave speed is constant?
Answer: If wave speed is constant, increasing the frequency will result in a decrease in wavelength, and vice versa.
Card 3
Question: What is the general wave function for a sinusoidal traveling wave propagating in the positive x-direction?
Answer: y(x, t) = A · sin(kx − ωt)
Card 4
Question: In the wave function y(x, t) = A · sin(kx − ωt), what does 'A' represent?
Answer: A is the amplitude, the maximum displacement of the particle.
Card 5
Question: How is the wave number (k) related to the wavelength (λ)?
Answer: k = 2π/λ
Card 6
Question: What does the wave number (k) represent and what are its units?
Answer: The wave number (k) represents the spatial frequency of the wave, measured in radians per meter (rad/m).
Card 7
Question: How is the angular frequency (ω) related to the frequency (f)?
Answer: ω = 2πf
Card 8
Question: What does the angular frequency (ω) represent and what are its units?
Answer: The angular frequency (ω) represents the temporal frequency of the wave, measured in radians per second (rad/s).
Card 9
Question: In the wave function y(x, t) = A · sin(kx − ωt), what does the term (kx − ωt) represent?
Answer: The term (kx − ωt) represents the phase of the wave.
Card 10
Question: What does a negative sign in the phase (kx − ωt) indicate about the direction of wave travel?
Answer: The negative sign indicates that the wave is traveling in the positive x-direction.
