Q.1 (e) Calculate the wavelength of de-Broglie waves associated with mass 1 kg moving with a speed of 103 m/sec.
Best answer
Given: \(m=1\) kg, \(v=10^3\) m/s, \(h=6.63\times10^{-34}\) J s.
Formula: \(\lambda=\dfrac{h}{mv}\)
\[ \lambda=\frac{6.63\times10^{-34}}{1\times10^3}=6.63\times10^{-37}\ \text{m} \]
\(\lambda=6.63\times10^{-37}\) m
This is far too small to detect, which is why the wave nature of macroscopic bodies is never observed.
