Lights acts as what? - Answer-Particle and wave. Wavelength - Answer-The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared (blue) Short - higher energy Long - lower energy Frequency (V) - Answer-The number of wavefronts per second. Highest: x-ray Velocity of Light - Answer-C = 3.00 X 10^8 = wavelength X frequency Amplitude - Answer-The intensity, height of peaks of waves. Highest: blue light Energy of Wave (J) - Answer-Increases as frequency increases and as wa...
