If it is between 390 and 700nm (nano meter) then yes.
Ultrasonic is sound of a higher pitch and shorter wavelength than humans can hear.
Inches (microwave) vs. Feet (Radar).
The wavelength used in the microwave oven is about 12 centimeters. (rounded) In the early days, there were radar systems that used wavelengths longer than that, but there haven't been any for several decades now.

Because in the visible-to-humans-(who call red, "red")-portion of the electromagnetic spectrum, the particular wavelength whose wavelength matches the wavelength of the color red looks red in color to the humans who call red "red" and not just a feeling. Red isn't even a feeling. What are you talking about?
Of the colors visible to humans, red light has the lowest wavelength. Violet light and white light have the highest wavelengths.
Small wavelength used in led bcoz we commonly use led as a flashlight.
no because the wavelength of the waves are too short for us to see

I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.

Resolving power of microscope is inversely related to the wavelength of the light used. So shorter the wavelength, greater the resolving power.

not for a long time. they are not very harmful as they have a long wavelength and a low frequency.
