Question

Compare a wave that has a period of 0.03 second with a second wave that has a period of 1⁄4 second. Which wave has the greater frequency? Be sure to show the steps for your work.

Answer 1

Answer:

The wave with 0.03 time period have the greater frequency

Explanation:

Given in the question,

Period T$_{1}$ of one wave = 0.03 seconds

Period T$_{2}$ of another wave = 1/4 seconds

We know that

T = 1 / f

So,

f$_{1}$ = 33.3 hz

f$_{2}$ = 4 hz

The wave with 0.03 time period have the greater frequency.

Answer 2

Answer:

The first wave has a frequency of 33.3 Hz:  

f1 = 1⁄T1  

f1 = 1⁄0.03  

f1 = 33. 3 Hz

The second wave has a frequency of 4 Hz. f2 = 1⁄T2  

f2 = 1⁄1⁄4  

f2 = 1 ÷ 1⁄4  

f2 = 1 × 4⁄1  

f2 = 1⁄1 × 4⁄1  

f2 = 4 Hz

Therefore, the first wave has a higher frequency.
