Interactions of Electromagnetic Waves with Charged Particles

The video tutorial explores the interaction of radio waves with electrons, explaining how alternating currents in electrical circuits produce radio waves. It discusses electromagnetic waves' role in changing electron energy levels and introduces nuclear radiation, focusing on gamma rays. The tutorial concludes with ionizing radiation's effects on living tissue and safety measures, including radiation dose measurement.

How are radio waves produced in electrical circuits?

• By static electricity

• By direct current

• By chemical reactions

• By oscillations in electrical circuits

What happens when an electron in an atom absorbs the right amount of energy?

• It jumps to a higher energy level

• It emits a photon

• It becomes a neutron

• It remains in the same energy level

What is gamma radiation an example of?

• Chemical radiation

• Thermal radiation

• Mechanical radiation

• Nuclear radiation

Why is ionizing radiation considered dangerous to living tissue?

• It causes cells to multiply rapidly

• It causes chemical reactions to stop

• It increases the temperature of the tissue

• It can remove electrons from atoms, altering chemical reactions

What is the unit used to measure radiation dose?

• Kelvin

• Sieverts

• Watts

• Joules
