Question

Calculate the properties of the waves below that are missing in the table. Drag the correct answers to the empty boxes in the table.

Answer 1

Explanation:

We calculate in each case for the first part:

Given:

Wavelenth (λ) = 3405

Period (T) = 620

`\begin{gathered} f=(1)/(T)=(1)/(620) \\ f=0.0016\text{ Hz} \\ \\ v=f\cdot\:\lambda=0.0016\cdot3405 \\ v=5.4\text{ m/s} \\ \\ E=(1)/(\lambda)=(1)/(3405) \\ E=0.00029\text{ J} \end{gathered}`

Now for the second part:

Given:

Wavelenth (λ) = 15.2

Velocity (v) = 25.3

`\begin{gathered} f=(v)/(\lambda)=(25.3)/(15.2) \\ f=1.7\text{ Hz} \\ \\ T=(1)/(f)=(1)/(1.7) \\ T=0.59\text{ s} \\ \\ E=(1)/(\lambda)=(1)/(15.2) \\ W=0.066 \end{gathered}`
