De Broglie Equation Recommended PYQs (STRICTLY NCERT Based) Structure of Atom Chemistry NEET Practice Questions, MCQs, Past Year Questions (PYQs), NCERT Questions, Question Bank, Class 11 and Class 12 Questions, and PDF solved with answers

Incorrect statement among the following is:

1.	The uncertainty principle is$\Delta x \cdot \Delta p \geq \frac{h}{4 \pi} $
2.	Half-filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry, and a more balanced arrangement.
3.	The energy of the 2s orbital is less than the energy of the 2p orbital in the case of hydrogen-like atoms.
4.	De-Broglie's wavelength is given by$\lambda=\frac{h}{m v} $, where m= mass of the particle, v = group velocity of the particle.

A 0.66 kg ball is moving with a speed of 100 m/s. The associated wavelength will be:

$(h = 6.6 \times 10^{- 34}$ $J s)$

1. $6.6 \times 10^{- 34} m$

2. $1.0 \times 10^{- 35}$ $m$

3. $1.0 \times 10^{- 32} m$

4. $6.6 \times 10^{- 32}$ $m$
