Which of the following statements about electromagnetic waves is incorrect?

The statement indicating that higher frequencies are often longer than lower frequencies is not accurate. In the context of electromagnetic waves, wavelength and frequency are inversely related; as the frequency of an electromagnetic wave increases, its wavelength decreases. This relationship is governed by the equation \(c = \lambda f\), where \(c\) is the speed of light, \(\lambda\) is wavelength, and \(f\) is frequency. Higher frequency waves, such as gamma rays, have much shorter wavelengths compared to lower frequency waves, such as radio waves, which have longer wavelengths. Thus, the assertion in this statement contradicts the fundamental principles of how electromagnetic waves function. The other statements convey correct information about electromagnetic waves. They can indeed have both long and short wavelengths, span a wide range from large distances to atomic scales, and exhibit dual behavior as both waves and particles, reflecting the principles of wave-particle duality in quantum physics.
