The amplitude and frequency of the resultant wave will be √2A . ω
Explanation:
As we know that resultant angular frequency
ω (resultant) = ω
A(resultant) = √A1^2 + A2^2 + A1A2 CosΘ
A(resultant) = √A^2 + A^2 + 2 AA X 0
= √2A
Now the amplitude and frequency of the resultant wave will be equal to
= √2A . ω
