NEET Physics de Broglie Wavelength Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) De Broglie wavelength for a ball | (i) Significant in macroscopic objects |
| (b) De Broglie wavelength for an electron | (ii) Measurable in sub-atomic domain |
| (c) Formula for de Broglie wavelength | (iii) l = h/p |
| (d) Momentum of a particle | (iv) p = mv |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The de Broglie wavelength for a macroscopic object like a ball is negligible and thus does not exhibit wave-like properties (a-i). In contrast, the wavelength for an electron is measurable and significant in the sub-atomic domain (b-ii). The formula for de Broglie wavelength is given by l = h/p (c-iii), and momentum is defined as p = mv (d-iv).
