An airplane weighing 80,000. kg at takeoff reaches a speed of 880 km/h. What is the de Broglie wavelength in meters of the plane?

3.39 * 10^-41 m

Explanation:

Given that:

speed of airplane = 880 km/hr

Mass of airplane = 80000 kg

Debroglie wavelength (λ) = h / mv

h = planck's constant = 6.626 * 10^-34

; mass = 80000kg

Velocity = 880km/hr to convert to m/s

Velocity = (880 * 1000m) / 3600 =244.44 m / s

λ = (6.626 * 10^-34) /(80000*244.44)

λ = (6.626 * 10^-34) / 19555200

λ = 3.3889 *10^-41

λ = 3.39 * 10^-41 m
