Question 1168307
.
<pre>

The light bubble and its length are irrelevant to the question.


The rest of the data do not define the form of the reflector with the necessity:


    It can be parabolic OR can be not parabolic,

    independently of and without connection with the given data.
</pre>


In other words, there is no &nbsp;"causal relationship" &nbsp;between the given data and the form of the reflector.
