Two waves are represented by y₁=A (k x- t) and y₂=A (k x- t) . The amplitude of resultant wave is
Options
- A4 A
- B2 A
- C2 A
- DA
Correct answer
C. 2 A
Step-by-step solution
Given, aligned & y₁=A (k x- t) & y₂=A (k x- t) aligned or y₂=A (k x- t+ 2 ) Phase difference of two waves = 2 Resultant amplitude aligned R & = A^2+A^2+2 A A & = A^2+A^2+2 A^2 2 & = 2 A^2 ( 2 =0 ) R & = 2 A aligned
