The displacement of an elastic wave is given by the function `y=3 sin omega t +4 cos omegat .`
where y is in cm and t is in second. Calculate the resultant amplitude.

Explanation

To calculate the resultant amplitude of the elastic wave given by the function \( y = 3 \sin(\omega t) + 4 \cos(\omega t) \), we can follow these steps:

### Step 1: Identify the components
The given wave can be split into two components:
- \( y_1 = 3 \sin(\omega t) \) with amplitude \( a_1 = 3 \)
- \( y_2 = 4 \cos(\omega t) \) with amplitude \( a_2 = 4 \)

### Step 2: Convert cosine to sine
