Question

The de Broglie wavelength of a tennis ball mass 60 g moving with a velocity of 10 m per second is approximately: (A) 10-16 m (B) 10-25 m (C) 10-33 m (D) 10-31 m

λ=(h/m v)=(6.626 × 10-34/60 × 10-3 × 10)=10-33

Q. The de Broglie wavelength of a tennis ball mass $60 g$ moving with a velocity of $10 m$ per second is approximately:

$1 0^{- 16} m$

$1 0^{- 25} m$

$1 0^{- 33} m$

$1 0^{- 31} m$

$λ = \frac{h}{m v} = \frac{6.626 \times 1 0 ^{- 34}}{60 \times 1 0 ^{- 3} \times 10} = 1 0^{- 33}$
