The image in the photograph is representing A. Analog Data. Analog data is data that is represented in a physical way. Where digital data is a set of individual symbols, analog data is stored in physical media, whether that's the surface grooves on a vinyl record, the magnetic tape of a VCR cassette, or other non-digital media. Analog and digital signals are different types which are mainly used to carry the data from one apparatus to another. Analog signals are continuous wave signals that change with time period whereas digital is a discrete signal is a nature. Examples of analog technology: photocopiers. old land-line telephones. audio tapes. old televisions (intensity and color information per scan line). Analog and digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals that have continuous electrical signals, while digital signals have non-continuous electrical signals.
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
