How can you tell with your eyes if two light waves have different frequencies?

We'd need a bit of information about the waves. If we knew the frequency, we'd know that the lower frequency wave had the greater (longer) wavelength. If we knew the period (the time for one cycle), we'd know that the one with the greater period would have the lower frequency and the greater (longer) wavelength. There might be some other things that would give us the answer, but we'd have to know what kind of wave we were dealing with. A mechanical wave like a wave on water or a sound wave? An electromagnetic wave? What was stated is true for all those waves.

Why is the sunlight reaching the earth yellowish?
Sunlight is actually light waves of different frequencies. Some of these waves are part of the visible light spectrum (ROYGBIV), and therefore sunlight appears white, a combination of all the frequencies in the visible light spectrum. Light waves with lower frequencies appear more red or orange. Light waves with higher frequencies appear violet or blue. When sunlight shines down through the atmosphere, the particles in the air scatter the light waves of higher frequencies, therefore spreading the waves in different directions in the sky (This is why the sky appears blue). The lower frequency waves reach our eyes mostly undisturbed. Since sunlight has light frequencies dominant in yellow, that's the color we see.
What are the detectors of visible light waves?
The eye and photosensitive paper both detect visible light.
The range of electromagnetic waves that human eyes can detect?
visible light spectrum
How are ultraviolet waves different from violet waves?
Ultraviolet (UV) light has a higher frequency (and a shorter wavelength and shorter period) than violet light. It is more energetic, too. We can't see UV light as our eyes only see up through violet. The shorter wavelengths of the UV light are something we cannot detect with our eyes. We can see (in order of increasing frequency) red, orange, yellow, green, blue and violet light. The UV light is outside the range of our vision.
What are light waves used for?
Their most important use is allowing us to see. Light waves react with chemicals in our eyes, which send signals to the brain, which creates the sensation of sight.

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 causes colour?
Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.
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 band of light waves in the electromagnetic spectrum that vibrates at frequencies our eyes can detect?
That's called visible light.
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.
What waves include the waves that your eyes see as different colors?
Visble Light
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 are electromagnetic frequencies to which are eyes are sensitive?
Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
What is the connection between the frequency wavelength and color of light?
Frequency = speed / wavelength. On the other hand, light of different frequencies looks to our eyes as different colors. Some frequencies - most, in fact - can't be seen at all.
What are the different type of wavelength band of colors in visible light?
There's only one "type" but the different frequencies are segregated as "color" by our eyes.
What part of the electromagnetic spectrum is most absorbed by water?
Water is cyan because it absorbs red light. The froth in the waves is white because, like clouds, it is composed of variety of tiny water droplets that scatter light of all the visible frequencies. Water is transparent to light of nearly all the visible frequencies, it strongly absorbs infrared waves. Water molecules resonate to the frequencies of infrared. Energy of the infrared waves is transformed into internal energy in the water, which causes red light to be a little more strongly absorbed in water than blue light. Electromagnetic waves that stimulate the sensation of color when the vibrations interact with the cone-shaped receiving antennae in the retinas of our eyes. Our eye-to brain interactions produce the beautiful colors we see.
