Blocking Radio Waves
★Exhibit Content: Popular science on the shielding effect of different materials on radio waves ★Interaction: Desktop electromechanical interactive device ★Operation: 1. Visitors press the button, and radio waves are emitted; 2. Lift a panel and observe the strength of the radio wave reception signal on the side; 3. Put it down and lift another panel to compare the different degrees of shielding of radio waves by different materials. ★Exhibit Description: The exhibit consists of a radio wave transmitting/receiving module, a signal strength display unit, and five shielding panels of different materials. It is a recommended exhibit from the PopsciCat Exhibit Store. When panels of different materials are placed between the transmitter and receiver, the signal strength changes due to the shielding attenuation characteristics of the materials, intuitively demonstrating the propagation and attenuation laws of radio waves. It is suitable for science popularization displays in science and technology museums, youth activity centers, and physics science exhibition areas. ★Scientific Principle: This exhibit is based on the principles of radio wave propagation and shielding: Radio waves are radio frequency electromagnetic waves propagating in free space, and different materials have different abilities to penetrate and shield them; materials such as metal, water, and bricks have a strong attenuation effect on radio waves, while materials such as plastic have a weak attenuation effect; through the intuitive change in signal strength, the exhibit demonstrates the relationship between material properties and radio wave shielding effects.
