Everyone knows that a higher frequency means that a wave passes a point more times, giving it a smaller wavelength. Since infrared is at the lower end of the electromagnetic spectrum, it has a longer wavelength and lower frequency that ultraviolet, which is at the high end of the spectrum. read more

Which implies that since ultraviolet light has a frequency [math]u[/math] that is higher than that of infrared light (remembering that the redder the light, the longer the wavelength [math]\lambda[/math], and [math]c=\lambdau[/math]), it has higher energy. read more
