Question

ball having mass 100g moves with velocity 100m/sec. Find out the value of wave length of base ball.

Answer 1

The wavelength can be calculated with the help of de-Broglies formula ie

Answer 2

From de broglie hypothesis,

Wavelength(λ)= h/p = h/(mv)

Here , m =100 g = 0.1kg

v = 100 m/s

And , h =6.626×10^-34

Then , λ = \( \frac{6.626×10^{-34}}{0.1×100}\)

And, λ=6.626×10^-35

Wavelength of the base ball 6.626×10^-35 m
