The velocity is related to wavelength and frequency, f, by. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa. decreases O c.) disappears Q d.) stays the same 9 It takes more energy to make pattern 6 than to make pattern 5. The equation can be rewritten to calculate wavelength (and frequency), speed of light and Plank constant. visible light. Briefly explain why each of the following statement is false, or reword it to make it true. The higher the frequency, the more energy, and the higher the amplitude, the more energy. 1 See answer Advertisement Advertisement PeriwinkleBlue PeriwinkleBlue A. Frequency (f) is a measure of how frequently a wave appears within a period of time. Wave Nature of Matter and De Broglies Equation. Patterns 5 and 6 have the same wavelength and frequency but the amplitude is different. Light of wavelength and frequency v passes through a single slit of width ( a ) .The diffraction pattern is observed on a screen a distance from the slit. The phenomenon of it was given by Planck known as Plancks law, E = h. Because the velocity is constant, any increase in frequency results in a subsequent decrease in wavelength. b. increases and energy increases.
