What is the De Broglie wavelength of an electron that strikes the back of the face of a TV screen at 19 the speed of light?
Assuming you mean that the velocity is 1/9th the speed of light then you need to use the de Broglie equation for the wavelength of a particle, which says that the wavelength is equal to Planck's constant divided by the momentum. Thus, λ = h / p = h / (m*v) = h/(m*1/9*c) = 9*h/(m*c) where λ=wavelength, h=Planck's constant, p=momentum, m=mass of the electron, v=velocity, and c=speed of light this gives λ = 9 * 6.626*10^-34 / (9.109*10^-31 * 3.00*10^8) = 2.18*10^-11 meters

Determine wavelength for electron having velocity 15.0 the speed of light?
Speed of electron as compared to speed of light is: n = 15% c = 299792458 [m/s] v = c*n/100 = 4.5 *10^7 [m/s] So corresponding wavelength as given by the de Broglie equation: h - Planck's constant, m0 - the mass of the electron at zero velocity; lambda = h/p = h/(v*m0) = 6.62606876*10^-34/(4.5 *10^7*9.10938188*10^-31) = 1.61642*10^-11 [m] = 0.16 [angstroms]
What is one half the speed of light?
The characteristic wavelength of an electron = h / p, where h = Planck's constant; p = the electron linear momentum = electron mass * speed = g * electron rest mass * speed; and g = the Lorentz factor to account for the electron-mass change with speed. Known facts: h = 6.63 × 10-34 [J s] electron rest mass, me = 9.11×10-31 [kg] electron speed, v = 1.5x108 [m/s] c = speed of light in vacuum = 3x108 [m/s] v/c = 0.5 g = 1/sqrt(1 - v2/c2) = 1/sqrt(0.75) = 1.1547 Therefore, p = 1.1547 * 9.11×10-31 [kg] * 1.5x108 [m/s] = 2.7e-29 [kg m s-1] Hence, the electron wavelength = 6.63 × 10-34 [J s] / 2.7e-29 [kg m s-1] = 2.46e-5 [m] or 2.46x10-5 [m].
