One way to do that is to silently move parts of your body in understood and agreed
patterns in order to convey signals to other people who see you as you do it. One
example of this strategy is: Wave at your friend across the street.
Because they are smaller than the wavelengths of visible light.
Yes, the wavelength of the light limits the maximum magnification of a microscope. Using visible light, the limit is about 1200 to 1500X.
As they sailed on, there was a visible light at the horizon.
Yes. (semaphore)
You can communicate with computers using the Light Pens And Graphics Tablets.
No.
A fluorescent light bulb converts ultraviolet waves into visible light using a phosphor coating inside the bulb. When the UV light hits the phosphor coating, it emits visible light.
No rainbows can only happen using visible (white) light.
Literally speaking, we do it every day, using the communications technique that we call 'radio'.Information carried by radio travels from place to place at the "speed of light".If you need an example of communication using nothing but visible light, thenyou'd have to consider something like waving at a friend across the street.But still, If we communicate through radio waves, to sound still takes time to reach our ears and get processed by the brain, taking up enough time.
astronomy using radio waves, rather than visible light. visible light and radio waves are essentially the same, only radio waves have a much longer wavelength. not everything emits light in the visible band, many otherwise invisible objects can only be detected using extreme wavelengths.
Atoms are typically smaller in size than the wavelength of visible light, which makes them difficult to detect using visible light. Additionally, atoms do not absorb or reflect visible light in a way that allows them to be seen by the human eye. Special techniques such as electron microscopes are often used to visualize atoms.
Infrared photography captures light in regions below the visible spectrum and renders it as a visible image. It involves using film or sensors sensitive to infrared light to create unique and ethereal images.
