A flash light is pointed at a wall so that the angle between the beam and the wall is 65 degrees(adsbygoogle = window.adsbygoogle || []).push({});

a) which conic section is produced? Im not sure if this is asking for the shape but I think the answer is an ellipse

b) How would you adjuct the angle of the beam to produce a circle on the wall? I think if the angle between the beam and the wall is 180 degrees than a circle will be produced on the wall

Can someone please help me out?
