If an electron has a wavelength, does it also have a colour?

Calculate the velocity of an electron having wavelength of 0.15 nm. Mass of an electron is 9.109 xx 10^(-28) grams.

Radiation of wavelength lambda is incident on a photocell.The fastest emitted electron has speed v.If wavelength is changed to (3lambda)/(4) the speed of the fastest emitted electron will be

Calculate the de-Broglie wavelength of an electron that has been accelerated from rest through a potential difference of 1 kV

If proton and electron have same de-Broglie wavelength then….

An electron (of mass m) and a photon have the same energy E in the range of few eV.The ratio of the de-Broglie wavelength associated with the electron and the wavelength of the photon is (c=speed of light in vaccum)

Wavelength of red colour is approximately how many times the wavelength of violet colour ?

Nomination of electron is 5200 A .At which velocity of electron its wavelength is equal to photon.

Electrons with de-Broglie wavelength lambda fall on the target in an X-ray tube. The cut-off wavelength of the emitted X-ray is
