What is the ratio of the de Broglie wavelength for an electron (m_e = 9.1 × 10^-31 kg) moving at a speed of 1.70 × 10⁴ m/s and a ball of a mass = 0.5 kg moving at a speed of 13 m/s? [h = 6.63 × 10^-34 Js] A)1.1 × 10²⁷ B)1.4 × 10²⁵ C)1.3 × 10^-28 D)1.3 × 10^-38

The de Broglie wavelength is given by λ = h / (mv). For the electron, λ_e = h / (m_e * v_e) and for the ball, λ_b = h / (m_b * v_b). The ratio λ_e / λ_b = (m_b * v_b) / (m_e * v_e). Substituting the given values, the ratio is approximately 1.1 × 10^27.
