white light
If the lights from all visible wavelengths are combined, they appear to be a white color.
infrared
Different frequencies of visible light are perceived as different colors.
Yes, visible light waves have higher frequencies than radio waves. Visible light waves fall within the range of frequencies on the electromagnetic spectrum that is higher than radio waves.
Yes,visible light is used. Frequencies of blue and red absorbed effectively
A mixture of all the visible frequencies.
their wavelengths (frequencies)
Violet
Visible light has shorter wavelengths than microwaves. Microwaves, which might be considered the highest energy radio waves, have a longer wavelength (and a lower frequency) than visible light.
Ultraviolet light extends for quite a ways up the electromagnetic spectrum after visible violet ends. Its frequencies are higher. Wavelengths from 400nm to 50nm covering 4 groups of UV.
Visible light. It has a higher frequency so more energy.
Any black object or surface.
