Answer 1

It would be C bc you do 12/4 so 3 waves per second

Answer 2

`\text{Hey there!}`

`\text{If 12 waves pass a point in 4 seconds, the frequency of vibration is:}`

`\text{In order for you to find out the frequency of vibration, you have to\underline{ DIVIDE} 12 from 4}`

`(12)/(4)\ = (12/4)/(4/4)\ = 12/4=3 \ \rightarrow4/4=1`

`\text{3}/\text{1 = 3}`

`\boxed{\boxed{\text{Answer: C.) 3}}}\checkmark`

`\text{Good luck on your assignment and enjoy your day!}`
