The correct answer = λ= 1.899*10^-34 m

Explanation:
Since,
Wavelength = λ = h / mv

Where h = Planck’s constant = 6.626*10^-34 Js
m = mass of golf ball = 45.9 g = 45.9*10^-3 kg
v = velocity of ball = 76.0 m/s
λ = wavelength= ?

Plug in the values we get:
λ= (6.626*10^-34) / ( 45.9*10^-3*76)
λ= 1.899*10^-34 m

Answer: 1.899×10^-34 m

Explanation:

Using de broglie's equation:

Wavelength (λ ) = h / mv

h = Planck’s constant = 6.626×10^-34 Js

m = mass = 45.9 g = 45.9×10^-3 kg

v = velocity = 76.0 m/s

λ = wavelength; which is the unknown

Subtituting the above and given values we have:

λ= (6.626×10^-34) / ( 45.9×10^-3 × 76)

λ= 1.899×10^-34 m
