As the energy of a photon increases, its frequency decreases. The relationship between wavelength and frequency is called an inverse relationship, because as the frequency increases, the wavelength decreases. Now, what is a wave? 9. 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. As the wavelength is a distance or length between two points, it is measured in meters, centimeters, millimeters, micrometers, Angstroms, etc. IV. southwest (that is, at 45 degree from directly south and from directly west), vector d2 for 0.50 m due east, vector d3 for 0.60 m at 60 degree north of east.
