Description of the Ellipse – Matemáticas 10°
by Cátedra SAS
Guillermo visits a scientific laboratory his uncle invited him to, enters a room that has the shape of an egg, and observes a scientist who is playing with a flashlight. He chooses a point on the room floor and turns on the flashlight projecting beams of light and changing the angle between the flashlight and the floor. The funny thing is that despite the angle change, when the beam of light bounces, it always ends up in the same place of the room, another marked spot. What property does this room have for this to happen? The teacher, using the platform as aid, shares the animation proposal about the use of the ellipses and its reflective property in the real world. The teacher asks about other elements that have the shape of an ellipse in their surroundings.
