PLS HELP ILL MARK BRAINLIEST A child is throwing stones at the center of a pool and would like to find the travelling speed of waves in water. Write an experimental design where the child can calculate the speed of wave.
Hint: Pool floor is built with foot long tiles.

You can calculate the distance and the amount of time it takes the child to throw the stones and the amount of force he is using.

Explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
