Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022. Question 7. Wavelength increases, while frequency and energy decreases as we go from gamma rays to radio waves. Scattering is not considered in the problem, as the cover is assumed to have an infinite length. An increase in the energy mismatch of the excitation wavelength and the plasmon resonance leads to a significant decrease in PM-PL. From the equation of the wavelength, we can tell that the wavelength of a wave is inversely proportional to its frequency, i.e., as the frequency of a wave increases, its wavelength decreases.

Radio waves have the largest wavelength (smallest frequency, smallest energy) while X-rays and gamma rays have the smallest wavelength (largest frequency, largest energy). Hence, the new wavelength of the wave is half of the old wavelength. 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. This is known as: as wavelength increases, frequency decreases and as wavelength decreases, frequency increases. Let f and F be the old and new frequencies of the light wave. So the longer the wavelengths and lower the frequency results in lower energy.
