Mastering the 90-Degree Wave Lag: A Quick and Easy Guide

[StudentofLife]

This has nothing to do with homework, so I hope this is OK

(I graduated college in 07 :) )

How do you draw one wave lagging another by 90 degrees?

My girlfriend and I can't remember how to draw this out.

wooooow, nevermind

that was extremely obvious

Hi there,

Thank you for sharing your question about drawing a 90-degree wave lag. While this topic may not be directly related to homework, it is always great to continue learning and refreshing our knowledge on different subjects.

To draw a 90-degree wave lag, you will first need to understand the concept of phase difference. This refers to the difference in the starting point or phase angle of two waves. In order to achieve a 90-degree phase difference, one wave must start at a point that is one-fourth of a cycle ahead of the other wave.

To draw this out, you can use a graph with time on the horizontal axis and amplitude on the vertical axis. The two waves will be represented as sinusoidal curves on the graph. The first wave will start at the origin (0,0) and move upwards, while the second wave will start at (0,0) and move to the right. The second wave will reach its peak when the first wave reaches its zero point, creating a 90-degree phase difference.

Another way to think about it is to imagine drawing a circle on the graph with the two waves intersecting at the top of the circle. The first wave will be at the 3 o'clock position and the second wave will be at the 12 o'clock position, creating a 90-degree angle.

I hope this helps you and your girlfriend to visualize and draw the 90-degree wave lag. Remember to always start one wave at the origin and the other at a point one-fourth of a cycle ahead to achieve the desired phase difference. Good luck!
