From de-Broglie equation, λ = (h/mv) = (6.6 × 10-34/0.66 × 100) = 10-35 m

Q. A $0.66 k g$ ball is moving with a speed of $100 m / s$ . The associated wavelength will be $(h = 6.6 \times 1 0^{- 34} J s)$

$6.6 \times 1 0^{- 34} m$

$1.0 \times 1 0^{- 35} m$

$1.0 \times 1 0^{- 32} m$

$6.6 \times 1 0^{- 32} m$

From de-Broglie equation,
$λ = \frac{h}{m v} = \frac{6.6 \times 1 0 ^{- 34}}{0.66 \times 100} = 1 0^{- 35} m$

Q. A 0.66kg ball is moving with a speed of 100m/s. The associated wavelength will be (h=6.6×10−34Js)

6.6×10−34m

1.0×10−35m

1.0×10−32m

6.6×10−32m
