Question

Match List I with List II.

| List-I | | List-II | |
|---|---|---|---|
| A. | $E=h
u$ | I. | de Broglie wavelength |
| B. | Diffraction and Interference | II. | Particle nature of light |
| C. | $\lambda=h/p$ | III. | Wave nature of light |
| D. | Compton effect | IV. | Energy of photon |

Accepted Answer

D. 1. Recall that $E = h
u$ gives the energy of a single light quantum, based on Planck's hypothesis — this represents the **energy of a photon**.
$$
E = h
u \;ightarrow\; 	ext{IV. Energy of photon}
$$

2. Since diffraction and interference occur only due to the superposition of wave amplitudes, they demonstrate light's **wave nature**.
$$
	ext{Diffraction \& Interference} \;ightarrow\; 	ext{III. Wave nature of light}
$$

3. The de Broglie relation connects a particle's wavelength to its momentum, describing matter's wave-like behaviour.
$$
\lambda = \frac{h}{p} \;ightarrow\; 	ext{I. de Broglie wavelength}
$$

4. Since the Compton effect involves photons colliding with electrons and exchanging momentum like particles, it confirms light's **particle nature**.
$$
	ext{Compton effect} \;ightarrow\; 	ext{II. Particle nature of light}
$$

Hence, the correct matching is A-IV, B-III, C-I, D-II — **option D**.
