What is the first step in making the periscope?

The first step is to prepare a piece of cardboard measuring 28 x 30 cm and two flat mirrors, each 6 cm in size.

How are the mirrors positioned inside the periscope?

The mirrors are positioned at a 45-degree angle to each other, facing opposite directions, allowing light to reflect between them.

Why is it important to be careful when using the cutter?

Using a cutter can be dangerous, especially for beginners. The video advises caution and recommends asking for help from an adult if necessary.

What is the purpose of the wrapping paper in the project?

The wrapping paper is used to cover the cardboard, giving the periscope a more polished and attractive appearance.

What are the dimensions of the viewing windows on the periscope?

The viewing windows are 4 x 5 cm in size, with a 1 cm gap from the top of the cardboard.

What principle of physics does the periscope demonstrate?

The periscope demonstrates the principle of light reflection, where light from an object reflects off the top mirror, then off the bottom mirror, allowing the viewer to see over an obstacle.

What is the main function of the periscope?

The periscope allows users to see objects above their line of sight by reflecting light through mirrors placed inside.

How is the cardboard folded to create the periscope structure?

The cardboard is scored along the lines marked for folding using a dull cutter, then bent to form a rectangular box structure.
