Question

What is the debroglie wavelenght ( in cm) of a 160g of cricket ball travelling in the speed of 140 km hr^-1

Answer 1

The De-Broglie Hypothesis states that all matter particles behave like waves even this concept extends the Wave-Particle Duality to all matter particles.

h = 6.626 × 10^-34Now ,a/c to de- Broglie equation wavelength Wavelength = h/mvNow mv = 0.1×10=1So ,wavelength =h =6.626 ×10^-34 m.

According to de Broglie equation.

Wave length = h/mv = 6.255 x 10-34/(0.1x10) = 6.824 x 10-34 m

Answer 2

$\huge \tt 6.82 \times {10}^{ - 34}$
