Question

A cricket ball of 0.5 kg is moving with a velocity of 100 m/sec. The wavelength associated with its motion is : (A)  1/100 cm  (B)  6.6× 10-34 m  (C)  1.32 × 10-35m  (D)  6.6× 10-28 m

From de-Broglie equation: λ =(h/mv)=(6.62× 10-34/0.5× 100) =1.32× 10-35 m

Q. A cricket ball of 0.5 kg is moving with a velocity of 100 m/sec. The wavelength associated with its motion is :

$1/100 c m$

$6.6 \times 10^{- 34} m$

$1.32 \times 10^{- 35} m$

$6.6 \times 10^{- 28} m$

From de-Broglie equation: $λ = \frac{h}{m v} = \frac{6.62 \times 10 ^{- 34}}{0.5 \times 100}$ $= 1.32 \times 10^{- 35} m$

Q. A cricket ball of 0.5 kg is moving with a velocity of 100 m/sec. The wavelength associated with its motion is :

1/100cm

6.6×10−34m

1.32×10−35m

6.6×10−28m

From de-Broglie equation: λ=mvh​=0.5×1006.62×10−34​ =1.32×10−35m

$1/100 c m$

$6.6 \times 10^{- 34} m$

$1.32 \times 10^{- 35} m$

$6.6 \times 10^{- 28} m$

From de-Broglie equation: $λ = \frac{h}{m v} = \frac{6.62 \times 10 ^{- 34}}{0.5 \times 100}$ $= 1.32 \times 10^{- 35} m$
