Stealth technology is not just one technology, but a lot of methods that decrease the distance that a vehicle can be detected by radar, sonar or other means.
Radar is a detection system that tracks the location, speed, and direction of a vehicle by sending out short bursts of radio waves, and then listening for an echo as the waves bounce off the vehicle. By measuring how long it takes for an echo to arrive back, and how much of a shift has occurred in the echo as compared to the transmitted signal, the distance to the vehicle, and its velocity can be tracked.One way an aircraft is made more stealthy is by reducing its radar cross section or the radar signature that an aircraft produces. Radar cross section is a measure of how detectable an aircraft is by radar.
Lux Ray/light meter
Black construction paper
Pen or pencil
Cut the construction paper to the right size
Tape the paper to the inside of the box
With the copy paper, make a cylinder a crumpled cylinder a v and a w.
Tape the flashlight to the inside of the box
Put the first shape in the box and close with the light meter inside the box.
Record the data
Repeat for every shape 3-4 times
My hypothesis was supported in the fact that the cylinder scattered the least and the W scattered the most.
Sources of error
The shapes not being in the same exact spot in the box every time could have slightly altered the results. The light meter may not be 100% accurate every time because it wasn’t professional quality.
