The Phenomena of photoelectric effect and Compton effect will conform

Options

A. Wave theory of light
B. Particle nature of light
C. Dual nature of light
D. Electromagnetic theory

Answer

To solve the question regarding the phenomena of the photoelectric effect and the Compton effect, we can follow these steps:

### Step 1: Understand the Photoelectric Effect
The photoelectric effect occurs when light of a certain frequency (or higher) shines on a metal surface, causing the emission of electrons from that surface. This phenomenon can be explained by the particle nature of light, where light is considered to consist of photons, each carrying a quantized amount of energy.

### Step 2: Understand the Compton Effect
The Compton effect refers to the scattering of X-rays or gamma rays by electrons, resulting in a change in wavelength of the scattered radiation. This effect also supports the particle nature of light, as it demonstrates that photons can collide with electrons and transfer energy and momentum, similar to particles.

### Step 3: Analyze the Implications
Both the photoelectric effect and the Compton effect provide evidence that light exhibits particle-like properties. They show that light can behave like a stream of particles (photons) rather than just a wave. This duality is a fundamental concept in quantum mechanics.

### Step 4: Conclusion
Based on the explanations of both effects, we can conclude that the phenomena of the photoelectric effect and the Compton effect confirm the particle nature of light.

### Final Answer
The correct answer is that the phenomena of the photoelectric effect and the Compton effect will confirm the **particle nature of light**.
