Question

Match List-I with List-II



Choose the correct answer from the options given below:

• (A) (II), (B) (1), (C) (III), (D) (IV)
• (A) (II), (B) (III), (C) (I), (D) (IV)
• (A) (I), (B) (II), (C) (IV), (D) (III)
• (A) (III), (B) (IV), (C) (I), (D) (II)

Hint:

Snell’s Law = Refractive Index; Meissner Effect = Perfect Dimagnetism; Brewster’s Law = Polarized Light; Photoelectric Effect = Quantum theory.

Answer 1

The Correct Option is B

Step 1: Understand each law/phenomenon.
- Snell's Law (A) defines the relationship between refractive indices and the angle of light when it transitions between materials; therefore, it corresponds to (II) Refractive Index.
- The Meissner Effect (B) is characterized by perfect diamagnetism, where a superconductor completely expels magnetic fields; thus, it corresponds to (I) Perfect Dimagnetism.
- Brewster's Law (C) defines the angle at which light with specific polarization is perfectly reflected; hence, it corresponds to (III) Polarized Light.
- The Photoelectric Effect (D) involves the emission of electrons from a material upon light exposure and is explained by quantum theory, corresponding to (IV) Quantum theory of light.
Step 2: Conclusion. Therefore, the correct associations are: \[\text{(A) (II), (B) (I), (C) (III), (D) (IV)}\]
Final Answer: \[ \boxed{\text{(A) (II), (B) (III), (C) (I), (D) (IV)}} \]
