Inconsistency when measuring intensity in "Wave" vs "Ray" setting.

[orejolaphet]

I noticed that between the two laser settings: "Wave" and "Ray", the intensity will not be measured for the "Ray" setting but will be measured for "Wave".

Should the behavior be same for both settings? Here is a screen shot of the "Wave" being measured

With out moving the location of the laser, only changing the setting to "Ray", we have

Notice the laser ray passes through the lens, but intensity not measured.

I think the solution to this problem will be to fix the capture radius of the probe to match the graphical look--then the discrepancy will have an obvious physical reason.

I'm recalling a reason a smaller hit area on the sensor is better--a larger hit area accentuates the discontinuity in the light ray hitting the sensor near the origin. Still, I think I should make the entire sensor region on the probe capture light, and then if the discontinuity is too distracting, then it should be fixed with math (though I think I am the only one that has noticed the discontinuity until now).

OK I matched the regions in the above commit. Here's a screencast with the new behavior and the corner cases/discontinuities I am aware of:

The other solution I considered would be to make the wave hit area match the ray hit area, so that a wave would only intersect if the ray would have. @ariel-phet can you review everything in this issue and advise?

The behavior in the comment above seems fine. Closing
