If the waves are **coherent**, then the resultant intensity is given by

I = I_{1} + I_{2} + 2 √(I_{1} I_{2} Cos Θ), where Θ is the phase difference between two waves.

If the waves are **coherent**, then the resultant intensity is given by

I = I_{1} + I_{2} + 2 √(I_{1} I_{2} Cos Θ), where Θ is the phase difference between two waves.

Is the equation for displacement in the n th second dimensionally correct?

S = u + a (n- 1/2)

**Answer:**

Yes

**See the explanation given by Vimal Raj**

If we notice the derivation of this formula

let t1=x
