Which of the following is NOT true for light modeled as a particle?
A)A particle of light is the photon.
B)The energy of a photon is proportional to the photon's frequency.
C)Wavenumber is inversely proportional to photon energy.
D)As the wavelength increases,photon energy decreases.
E)The product of frequency and Planck's constant equals photon energy.

C) is not true because wavenumber is directly proportional to photon energy, not inversely. The energy of a photon is given by E = hf, where h is Planck's constant and f is the frequency. Since frequency is inversely proportional to wavelength (λ), and wavenumber is defined as 1/λ, it implies that as wavenumber increases, the frequency increases, and thus the energy of the photon increases as well.
