Relationship between light amplitude and intensity

Click For Summary
SUMMARY

The relationship between light amplitude and intensity is defined by the principle that light intensity is proportional to the square of the wave amplitude. This means that as the amplitude of a light wave increases, its intensity increases quadratically. Therefore, if one knows the amplitude of a light wave, the intensity can be calculated by squaring that amplitude.

what is the relationship between amplitude and intensity...is intensity just the amplitude squared?

Light intensity is proportional to the square of wave amplitude. So you are correct :)
