Dave and Kirk are learning about electromagnetic waves in class. Dave says that gamma rays are the most dangerous because they come from outer space. Kirk disagrees. Kirk says that gamma rays are not as dangerous as ultraviolet waves since they cause sunburn. Who is right and why?

Dave is partly right in his answer that gamma rays are the most dangerous, but it is because of their frequency and wavelength, not where they come from.

Neither are right because X-rays have radiation and are the most dangerous. That is why you have to wear a lead vest when you get dental x-rays.

Neither are right. Microwaves are the most dangerous because they have the longest wavelength and the biggest frequency. Microwave kill all living things.

Kirk is right. Ultraviolet waves cause sunburn and that can be very dangerous. Too much sun can cause skin cancer.

I'd say A: Dave is partly right in his answer that gamma rays are the most dangerous, but it is because of their frequency and wavelength, not where they come from.

Gamma rays are the most intense and thus, most harmful electromagnetic waves. Gamma rays radiation poisoning is difficult to shield against. These rays have the most energy and can go through six feet of concrete and damage your DNA as well. The higher the energy waves (gamma, x-ray), the shorter the wavelengths
