- Sunburn is caused by ultraviolet UV radiation. Why does red light not cause sunburn?arrow_forwardThe ultraviolet spectrum can be divided into three regions based on wavelength: UV-A (315–400 nm), UV-B (280–315 nm), and UV-C (100–280 nm).Photons from which region have the highest energy and therefore are the most harmful to living tissue?arrow_forwardUV-C light is necessary for the formation of ozone. Above the stratosphere, there is a greater amount of UV-C light than in the mid-stratosphere. Briefly explain why the ozone layer is found in the mid-stratosphere and not above the stratosphere (where there is the most UV-C light).arrow_forward
- Describe briefly the atomic or molecular processes involved in the production of X -rays and Infrared radiation.arrow_forward9. A few people in your neighborhood are protesting the erection of a 5G cell tower. They claim the radio waves from the tower will be damaging to human health, specifically leading to headaches, migraines, and dizziness. Using what you know about electromagnetic radiation and how it interacts with matter, which side of the protest would you be on? Why? Consider where radio waves fall on the electromagnetic spectrum and how you've seen radiation interact with parts the human body throughout this unit. (Note: this is something that really happened in Prof. Kerstiens' neighborhood. Also note that this does not include concerns about 5G power usage, impact on ecosystems, or waste production in making new cell towers and equipment.)arrow_forwardIt takes 348. kJ/mol to break a carbon-carbon single bond. Calculate the maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon. In nanometers (nm)arrow_forward
