@100% is 100% Correct as of April 27th, 2023. THANKS BUD.

The best answer for 1 is microwaves.

The best answer for 2, from the choices given, is 730 nm.
I'm skittish about the 730 since I've always been taught that the sensitivity for the eye ranges from 400 to 700 nm. But 600 nm is much more orange than red. 650 nm is about the low end for red. So assuming that the eye can SEE as high as 730 nm that is the choice.

To determine which type of electromagnetic radiation (EMR) is the most harmful among the given options (visible light, infrared light, microwaves, and radio waves), we need to consider the energy and frequency associated with each type.

EMR with higher energy and higher frequency tends to be more harmful to living organisms. Therefore, to figure out the most harmful EMR, we need to look at the electromagnetic spectrum and determine the types of radiation that fall within it.

The electromagnetic spectrum ranges from high-energy gamma rays to low-energy radio waves. As we move from left to right on the spectrum, the energy and frequency increase.

In general, visible light, which is the only option provided in the visible range, is not considered harmful to living organisms. It is the range of EMR that is visible to the human eye and includes various colors: red, orange, yellow, green, blue, indigo, and violet. Visible light allows us to perceive our surroundings and is essential for our vision.

Infrared light, microwaves, and radio waves, on the other hand, have longer wavelengths and lower energy compared to visible light. They are generally considered to be non-ionizing radiation, meaning they lack the energy required to remove tightly bound electrons from atoms or molecules.

While these types of EMR are generally considered to be safe, it's important to note that excessive exposure to any form of radiation can be harmful. For example, prolonged and direct exposure to high-powered infrared light sources (e.g., lasers) can cause tissue damage and burns. Similarly, long-term exposure to high-powered microwaves or radio waves can lead to tissue heating and possible biological effects.

Given this information, it is difficult to say definitively which of the given options (infrared light, microwaves, and radio waves) is the most harmful as it depends on the intensity and duration of exposure. However, visible light is generally not considered harmful.

Now, let's move on to determining the wavelength of visible light that is most likely seen as the color red among the given options (600 nm, 450 nm, 730 nm, and 520 nm).

The color perceived by the human eye corresponds to a specific range of wavelengths within the visible light spectrum. As mentioned earlier, visible light ranges from approximately 400 nm (violet) to 750 nm (red). Each color within this range is associated with a different wavelength.

Among the given options (600 nm, 450 nm, 730 nm, and 520 nm), the wavelength most likely seen as the color red is 730 nm. This falls within the red range of the visible light spectrum, which is typically associated with longer wavelengths.

To determine this, it is helpful to remember that wavelengths in the visible light spectrum become longer as we move from blue to red. Therefore, 730 nm is the most likely wavelength associated with the color red in this context.

In summary, visible light is generally not considered harmful compared to other types of EMR. As for the wavelength most likely seen as the color red, it is 730 nm from the given options.
