Guys does the format of article remain same ? or it varies with the Content ?
If it remains Same then , Is the following Structure Correct ?
1. Title
2. Question to create interest
3. Transition
4. Advantages with supports
5. Disadvantages with supports
6. Conclusion

Find time for one complete wave to form which is the time period T = 1/f ; T =1/0.5 = 21
Now time for one wave is 2s but there are 1.5 waves on the screen
So time for 1.5 waves to form is 1.5*2 = 3s
