WebThe De Broglie Wavelength gives the wavelength of any particle traveling with linear momentum. It shows an inverse relationship between the linear momentum and … Web3.1 de Broglie Waves Recall that a photon has energy E=hf, momentum p=hf/c=h/ , and a wavelength =h/p. De Broglie postulated that these equations also apply to particles. In particular, a particle of mass m moving with velocity v has a de Broglie wavelength of λ = h mv. where m is the relativistic mass m = m 1-v / c 0 . 22

Web7 The effect of diffraction is more noticeable, in everyday life, with sound than with light. This is because A sound has a much longer wavelength than light. B sound is a longitudinal wave, light is a transverse wave. C sound is a mechanical wave, light is an electromagnetic wave. D sound travels more slowly in air than light does.
