Final answer:
To calculate the wavelength of an electron, you can use the de Broglie wavelength equation, which states that the wavelength of a particle is equal to Planck's constant (h) divided by the momentum of the particle.
Step-by-step explanation:
To calculate the wavelength of an electron, we can use the de Broglie wavelength equation, which states that the wavelength of a particle is equal to Planck's constant (h) divided by the momentum of the particle. The momentum of an electron is calculated by multiplying its mass (m) by its velocity (v). In this case, the mass of an electron is 9.11 × 10-31 kg and its velocity is 1.85 × 107 m/s. Plugging these values into the equation, we have:
Wavelength = h / (m * v)
Wavelength = 6.626 × 10-34 J·s / (9.11 × 10-31 kg * 1.85 × 107 m/s)
Calculating the values will give you the wavelength of an electron traveling at 1.85 × 107 m/s.
