A third similar laser emits light with intensity 1.5Wm −2. Work out the amplitude of the light.
Im confused on how to do this. Any help?

Having the whole question and any previous answers in that question helps. Context and flow matters: generally, you're supposed to use previous answers to get to the next few within the same question.
Intensity varies proportionally with A². I don't what other information you have so that's all the help can be given.
