| 31. | About focusing : See curved mirror-a perfectly focusing mirror is actually paraboloid, not spherical.
|
| 32. | The "'flux density is increased "'near the edge of the paraboloid.
|
| 33. | The circular paraboloid that collects sound waves and directs those waves towards the owl's ears.
|
| 34. | This allows us to use a paraboloid frustum where that form appears more appropriate than a cone.
|
| 35. | Strictly, the three-dimensional shape of the reflector is called a " paraboloid ".
|
| 36. | The rotation shapes them into paraboloids that are accurate enough to be used as primary reflectors in telescopes.
|
| 37. | Unusually for a radio telescope, the primary reflector is an off-axis segment of a paraboloid.
|
| 38. | The paraboloid focuses through a central hole in the feed flat to a convenient distance behind the flat.
|
| 39. | Other interesting structures that he designed included the shells ( hyperbolic paraboloid ) for the Cairo International Fair.
