Why we can see thing?
Because we have eyes that are sensitive to and can focus light.
Are sun's radiations UV or infrared?
Yes ... it radiates across all frequencies, with a max output in the visible range.
How does light allow us to see?
Objects absorb light at certain frequencies and reflects light at other frequencies. The reason we see colours is because that is the frequency of light reflected, the reason we see black is because all colours are absorbed....it's nothing. So the reason we see objects is because light is reflected from them, this light then meets our eyes and creates an image.
Why do you get blind spots?
We have blind spots because part of the retina in our eye do not have light sensitive cells. Fortunately, we are not aware of our blind spots because the blind spots of our two eyes do not coincide.
At what frequency does SETI listen at?
SETI listens to frequencies between 1420 (the Hydrogen molecule) and 1662 (the hydroxyl molecule). This is to say that an intelligent civilization would recognize these frequencies and would probably be monitoring them a well. The cosmos is full of these frequencies and a slight deviation in the regular pulsing of these frequencies would be noticed by anyone who is scanning the skies. Hope this helps. Sam Farina III
The color of light is determined by of the light waves.?
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.
At what frequencies do advertisers concentrate the commercials sound?
At frequencies in which the ears are the most sensitive.
Why do you see white light?
White light is a mixture of different frequencies, that are within the range of light our eyes can see.
What type of electromagnetic waves are your eyes sensitive to?
Those in the range of spectral wavelengths labeled "visible light".
What is the difference between light waves and electromagnetic waves?
Light is ONE SMALL RANGE of the electromagnetic spectrum. In other words, electromagnetic waves within a relatively small range of frequencies - the frequencies that we are adapted to seeing with our eyes - is called "visible light", or simply "light".
What is the range of frequencies?
there are an infinite range of frequencies limited only by the mechanical limitations of the medium creating and transferring it.
What range of frequencies can be heard by a human?
Hearing Range of frequencies for humar ears if from 20 Hz to 20,000 Hz.
A simile for eyes and mirror?
as sensitive as mirror
What frequencies falls in the range of RF waves used by commercial controlled by the?
No frequencies in that range appear on the list you provided with the question.
Why do scientists use frequencies in the UHF range?
they use frequencies in uhf range since animals dont make those sounds
What is the frequency for a light wave?
You can see electromagnetic waves with frequencies between roughly 4.3 x 1014 Hzand 7.5 x 1014 Hz. Those are the waves we call 'light'. Different frequencies in thisrange are perceived as different colors. Outside this range of frequencies, the wavesare still there, but your eyes don't know it.
What are sound waves with frequencies below normal range?
Infrasounds (frequencies under 20 kHz)
