Electrons can be accelerated to high speeds in particle accelerators. At what speed does an electron have to move in m.s⁻¹ to have the same wavelength as red light? Assume that the wavelength of red light is 725 nm. The mass of an electron is 9.109 x 10⁻³¹ kg. [The answer is in m.s⁻¹. Do not type in the unit. Use a decimal point. Round your answer to three decimal places, for example 2.000E-10 or 1.140.]
