While the absolute value of the magnitude of one wave at any point is not very important, the relative displacement of two waves, called the phase difference, is vitally important because it determines whether the waves reinforce or interfere with each other. = (3.0 x 10^8 m/s) / (4.5 x 20^9 s^-1) If the frequency of a radio wave is 4.5GHz, what is the wavelength of the wave (velocity of light=3x10m/s)? To get an idea of the de-Broglie wavelength associated with macroscopic particles: Let us find the wavelength of a wave associated with a car of mass \(1000 \mathrm{~kg}\) moving with the velocity of \(10 \mathrm{~m} / \mathrm{s}.\), The wavelength associated with the car will be: \(\lambda = \frac{{\rm{h}}}{{{\rm{mv}}}}\), \(\lambda=\frac{6.62607 \times 10^{-34} \mathrm{Js}}{1000 \mathrm{~kg} \times 10 \mathrm{~m} / \mathrm{s}}=6.6 \times 10^{-30} \mathrm{~m}=6.6 \times 10^{-21} \mathrm{~nm}\). The Wavelength of a Black Body calculator compute the wavelength of the strongest emissions from a black body based on its temperature. It assumes that the wave is traveling at the speed of light which is the case for most wireless signals.

The mass of an electron is m e = 9.109 x 10 (-31) kg. },{ Determine: (a) the wave's amplitude, wavelength, and frequency. Because the mass of the electron at rest (\(m\)) is both constant and accurately known, the uncertainty in \((mv)\) must be due to the \(v\) term, which would have to be infinitely large for \((mv)\) to equal infinity. Conversely, the more accurately we know the precise momentum (and the energy) of the electron [as \((mv) 0\)], then \(x \) and we have no idea where the electron is. One could also express mv as the particle's momentum. He hypothesized that the electron behaves like a standing wave (a wave that does not travel in space). A pattern of constructive and destructive interference is obtained when two (or more) diffracting waves interact with each other.
