- Diffraction of light
- Refraction of light
- Compton effect
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand wave theory of light.
Wave theory successfully explains:
• Reflection
• Refraction
• Diffraction
• Interference because these are wave phenomena.
Step 2: Analyze the given options.
Reflection of light Can be explained using wave theory. \[ \Rightarrow \mathrm{Explained} \] Diffraction of light A pure wave phenomenon. \[ \Rightarrow \mathrm{Explained} \] Refraction of light Explained by wave propagation in different media. \[ \Rightarrow \mathrm{Explained} \] Compton effect Compton effect involves collision between photons and electrons and supports particle nature of light. Wave theory fails to explain it. \[ \Rightarrow \mathrm{Not\ Explained} \]
Step 3: Identify the correct option.
Therefore, the phenomenon that cannot be explained by wave theory is: \[ \boxed{\mathrm{Compton\ Effect}} \] Hence, the correct answer is: \[ \boxed{\mathrm{(D)}} \]
