Wavelength is the distance between two successive points of a wave that are in phase. Think of it as the length of one complete wave cycle. For example, in a sine wave on a graph, the wavelength is the distance fro By Dr. Otis Collins
• Jul 2, 2026 wavelength frequency and energy problems answer key . Solution Approach: Use: \[ E = h \times f \] Calculate: \[ E = 6.626 \times 10^{-34} \times 6.00 \times 10^{14} = 3.976 \times 10^{-19}\, \text{J} \] This energy corresponds to visible light in the red-orange spectrum.
