    • What is the definition of frequency?
      Number of wave cycles per second
    • How is wavelength measured?
      In meters (m)
    • What is the relationship between wavelength and frequency of electromagnetic radiation?
      • Wavelength and frequency are inversely proportional
      • As wavelength increases, frequency decreases
      • As wavelength decreases, frequency increases
    • How can you calculate the frequency of electromagnetic radiation if you know its wavelength?
      • Use the formula: f=f =c/λ c/\lambda
      • f = frequency
      • c = speed of light (3 x 10^8 m/s)
      • λ = wavelength
    • If a rope is moved up and down to create a wave, what does the amplitude represent?
      Height of the wave's peak from center
    • In the equation λ=\lambda =vf \frac{v}{f}, what does v represent?

      Wave speed
    • What are the components of the frequency definition table?
      • Term: Frequency
      • Definition: Number of wave cycles per second
      • Unit: Hertz (Hz)
      • Example: 5 texts per hour
    • Why does the frequency of electromagnetic radiation change as the wavelength changes?
      Because the speed of electromagnetic radiation is constant

      Square of the amplitude
    • What is the relationship between wavelength and frequency?
      They are inversely related.
    • What is the relationship between the amplitude (ΔE) and the wavelength of electromagnetic radiation?
      The amplitude (ΔE) does not depend on the wavelength
    • What is the relationship between amplitude and intensity shown in the image?
      • Amplitude refers to the maximum displacement from the midpoint of the wave
      • Intensity refers to the power or energy per unit area of the wave
      • The image shows that amplitude and intensity are related, with higher amplitudes corresponding to higher intensities
    • How does an increase in wavelength affect frequency?
      It decreases frequency.
    • In the equation λ=\lambda =vf \frac{v}{f}, what does λ represent?

      Wavelength
    • What is the relationship between amplitude and wave intensity?
      • Bigger amplitude means stronger wave intensity
      • Increased amplitude results in more energy
      • Example: louder sounds have larger amplitudes
    • How can frequency be illustrated in everyday life?
      By counting how often a friend texts
    • In the equation λ=\lambda =vf \frac{v}{f}, what does f represent?

      Frequency
    • If a friend texts you 5 times in an hour, what is the frequency of texts?
      5 Hz
    • How does the wavelength of electromagnetic radiation affect its frequency?
      • Long wavelength corresponds to low frequency
      • Short wavelength corresponds to high frequency
      • The product of wavelength and frequency is constant
    • How do shorter wavelengths affect frequency according to the study material?
      They result in higher frequencies.
    • How does doubling the amplitude affect wave intensity?
      It quadruples the wave intensity
    • What happens to the sound when you whisper?
      The sound becomes quieter due to smaller amplitude
    • How do longer wavelengths affect frequency according to the study material?
      They result in lower frequencies.
    • What are the definitions and units of key wave terms?
      • Amplitude: Maximum displacement from rest position (Meters)
      • Wavelength: Distance between two corresponding points on adjacent waves (Meters)
      • Frequency: Number of wave cycles per second (Hertz)
    • What does the graph in Figure 1 represent?
      • The graph shows the variation of amplitude and intensity over time
      • The blue line represents the amplitude of the wave
      • The red line represents the intensity of the wave
    • What is the significance of the relationship between wavelength and frequency?
      • Inversely related: as one increases, the other decreases
