(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Sorry if this comes out the wrong way, but I have to translate my problem from norwegian to english... but I'll give it a shot ;)

Task 1a was to find some maximal and minimal amplitudes.

Those I found: max 30 units and min 10s unit.

Task 1b is to use these amplitudes to find the contrast of the sinusoidal grating.

This I havenoidea how to do.

Can someone please show me what to do - and also explain what you do and why you do it?

2. Relevant equations

perhaps: h sin ø = lamda ?

But then again, what has lamda to do with any of this? :S

3. The attempt at a solution
