Given below are two statements: 
Assertion (A): Corpuscular theory fails in explaining the velocities of light in air and water.
Reason (R): According to corpuscular theory, light should travel faster in denser media than in rarer media.
 
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.

Sound waves travel faster in water than in air. Imagine a plane sound wavefront incident at an angle \(\alpha\) at the air-water interface; the refracted wavefront making an angle \(\beta\) with the interface. Then,
             
 
1. \(\alpha>\beta\)
2. \(\beta>\alpha\)
3. \(\alpha=\beta\)
4. the relation between \(\alpha~\&~\beta \) cannot be predicted.
