Electrons Emerge from an Electron Gun with a Speed of 2.0

question 120

Multiple Choice

Electrons emerge from an electron gun with a speed of 2.0 × 10⁶ m/s and then pass through a double-slit apparatus.Interference fringes with spacing of 2.7 mm are detected on a screen far from the double slit.What would the fringe spacing be if the electrons were replaced by neutrons with the same speed? (h = 6.626 × 10^-34 J ∙ s,m_electron = 9.11 × 10^-31 kg,m_neutron = 1.675 × 10^-27 kg)

• A)1.5 μm
• B)4.9 m
• C)0.93 nm
• D)1.2 km
