When it comes to telescope mirrors, larger is generally better. The larger your main mirror, the more light you can capture ...

You cannot simply use a bowl or other curved object as the precise parabolic shape ensures that sound waves are reflected onto one finite focal point. For this build the reflector was obtained ...

Schematic diagram of a parabolic reflector. Incoming sound is directed to the microphone placed at the focus of the parabola-shaped reflector. The property of the parabolic shape to reflect all sound ...

Here´s where the vacuum is needed to force the film into parabolic shape. Extract the air from a little hole in the lid that was previously drilled, and tape it to prevent the loss of the vacuum.

A light rigid structure (of aluminum or other material) which reflects sound to a focus at which a MICROPHONE is placed. This focussing effect is very strong with WAVELENGTHs less than the aperture of ...

Learn the parabola equation and its many versatile applications. A parabola is a symmetrical, U-shaped curve. It is a type of conic section, a geometric shape that forms through the intersection ...

the 2D curve of the Lovell Telescope dish is a parabola. It is this shape and structure that allows the telescope to gather incoming radio waves. When the telescope is pointed towards a radio ...
