The degree of interaction between water and microwaves is much greater than that between the former and visible light. As such, microwaves heat up water while visible light does not -- visible either goes though water or bounces off it.
Since our bodies consist of a lot of water, microwaves hitting us would cause us to heat up fairly rapidly -- exactly like food in a microwave oven.
Getting cooked in a microwave oven is a LOT more dangerous than being illuminated by a lot of visible light.
Microwaves can penetrate deeper into tissues and cause heating effects, leading to burns or tissue damage. Visible light, on the other hand, has lower energy and does not penetrate as deeply into the body, so it is generally not harmful at normal exposure levels.

Why is exposure to UV radiation dangerous whereas light does not harm us?
UV radiation has shorter wavelengths and higher energy compared to visible light, which can damage DNA in skin cells leading to mutations and potential skin cancer. Visible light has longer wavelengths and less energy, so it does not have the same level of harmful effects on DNA.
Is light visible or invisible and why?
Light is visible because it is composed of electromagnetic waves that fall within the visible spectrum, which our eyes are able to detect. When light strikes an object, it can be absorbed or reflected, allowing us to see the object.
Visible light it can be used for?
It aids in helping us to see stuff.
What is a visible object that is not a light source?
A visible object that is not a light source is any other object in the universe. Objects that are not light sources reflect light and are thus made to be visible.Examples include:planetspeoplethe mooncarsdogsflowersbooksrocks, either in daylight, or else illuminated by a flashlighta light bulb or LED with the power switched off
What is the definition of visible light waves?
Visible light waves are a form of electromagnetic radiation that can be seen by the human eye. They have wavelengths in the range of approximately 400 to 700 nanometers, and the different wavelengths correspond to different colors that we perceive in the world around us.
Are microwaves visible to humans?
No, microwaves are not visible to the human eye. They have a longer wavelength than visible light, which prevents us from seeing them.
Is light visible or not?
Only a small piece of the light spectrum is visible to us.
Why is exposure to UV radiation dangerous whereas light does not harm us?
UV radiation has shorter wavelengths and higher energy compared to visible light, which can damage DNA in skin cells leading to mutations and potential skin cancer. Visible light has longer wavelengths and less energy, so it does not have the same level of harmful effects on DNA.
Why does ultraviolet light have a big effect on us but visible light doesn't?
it have more energy than visible light
Is normal light visible to us?
One reason 'Normal Light' has that name is because it is visible to us and useful to us in so many different ways
Who invented visible light?
Visible light doesn't have to be invented. Light is a naturally occurring phenomenon under some circumstances, and the part that us humans can see we call "visible light".
How do Visible light waves with longer wavelengths look?
The light with the longest wavelength, which is still visible for us, is red light.
What type of energy is visible?
Visible light is a form of electromagnetic energy that is visible to the human eye. It is a type of radiant energy that allows us to see the world around us.
How Does the EM radiation plays significant roles in our life and why?
Electromagnetic radiation plays significant roles in our lives as it includes forms of energy like radio waves, microwaves, visible light, and X-rays which are essential for communication (radio waves), cooking (microwaves), vision (visible light), and medical imaging (X-rays). These forms of EM radiation allow us to transmit information, see the world around us, heat food, and diagnose medical conditions, making them indispensable for modern life.
Is light visible or invisible and why?
Light is visible because it is composed of electromagnetic waves that fall within the visible spectrum, which our eyes are able to detect. When light strikes an object, it can be absorbed or reflected, allowing us to see the object.
What is IR light?
Infrared light is electromagnetic radiation and is invisible to us. Other types of invisible light are microwaves, radio, gamma rays, x-rays, and ultraviolet light.
What makes a star visible?
A star is visible when it emits light, which can be detected by our eyes or instruments like telescopes. The distance between the star and Earth, as well as the brightness of the star, can affect how easily it is visible to us.
