Quiz zum Vortrag
What is an ionizing radiation?
- Radiation that can detach electrons from atoms and molecules, thereby ionizing them
- Radiation which can be absorbed by matter
- Radiation which can collide with ions
- Radiation which is positively charged
- Radiation which is negatively charged
Which of the following electromagnetic waves can be dangerous even at low intensities?
- Ultraviolet light
- Microwave
- Radio waves
- Red light
- Green light
Which type of electromagnetic wave is good for transmitting signals over long distances and why?
- Radio waves, as they have very long wavelengths they rarely interact with the surrounding
- Gamma rays, as they can penetrate through materials easily
- Microwaves, as they rarely interact with matter
- Infrared light, similar to how with infrared goggles it is possible to see through walls, infrared light can be used to transmit signals over long distances as they rarely interact with objects
- Ultraviolet light, as it can penetrate miles through the atmosphere and reach our skin from the sun, it can similarly be used to send signals over long distances through the atmosphere
