no bats and many marine animals can hear high frequency noises We can't. Most other animals can't
If the reference is to animal volcalizations, absolutely.
infrared
Different frequencies of visible light are perceived as different colors.
Yes,visible light is used. Frequencies of blue and red absorbed effectively
That his wife had been hard at work clearing the garage was clearly visible. The impact with the post left a visible dent in the rear of his car. Humans and most other mammals can only see the frequencies of visible light.
white light
A mixture of all the visible frequencies.
the range of visible light.
their wavelengths (frequencies)
Bonds in molecules absorb light, In black the bonds absorb a lot of visible light frequencies. As black only reflects few frequencies of visible light. it gains it black colour.
Many things can be sensed by humans - too many to name all of them!Some things that you can sense are visible light, sound within a certain set of frequencies, touch, and taste.
Violet
The cones in the retina of our eyes are sensitive to certain frequencies of light within the visible light spectrum (ROYGBIV). Light waves with longer wavelengths (within the visible range of frequencies) are perceived to be on the red, orange, yellow side of the spectrum, while higher frequencies/shorter wavelengths of light appear blue or violet.
