For a long time, that was the only means available to them.
It's only been comparatively recently that we've had instruments able to detect
and measure radio waves from space, or ways to hoist infra-red detectors, ultraviolet
detectors, x-ray detectors, and gamma ray detectors up above the atmosphere.
Fire doesn't use visible light. It producesvisible light.
The answer is visible light. Visible light is light that can be seen with a naked eye
Cyclists should use a white front light and a red rear light to ensure they are visible to other motorists.
The light microscope use the visible light; the electron microscope use an electrons beam.
Plants use visible light in photosynthesis by absorbing it through pigments like chlorophyll in their chloroplasts. This light energy is then converted into chemical energy in the form of glucose, through a series of biochemical reactions, which serves as fuel for the plant's growth and development.

The first use is simply seeing.
To see things.
Human beings use visible light for seeing; green plants use it for photosynthesis. It can also be used to generate electricity, by means of photo-electric cells.
Visible light cannot be used to see molecules because the wavelength of visible light is much larger than the size of molecules. This means that visible light cannot resolve the small details of molecules, making them invisible to the human eye.
Visible light
Visible light is used for various purposes such as lighting, photography, and communication. It is essential for vision and allows us to see colors and shapes. In technology, visible light is used in fiber optic communication and optical sensors.
