Given:
The ball of mass 0.2 kg moves with a velocity of 10 m/s.
To find:
What will be the wavelength of ball ?
Solution:
From the given information, we have the data as follows.
The ball of mass 0.2 kg moves with a velocity of 10 m/s.
⇒ m = 0.2 kg
⇒ v = 10 m/s
The formula that relates the wavelength and velocity is given as follows.
λ = h/mν
Substitute the values in the above equation.
λ = (6.63 × 10^{-34}) / (0.2 × 10)
λ = 6.626 × 10^{-34} m
Therefore, the wavelength of ball is 6.626 × 10^{-34} m
