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.
If colors have different wavelengths do they have different frequencies and temperatures?
Yes, light is electromagnetic waves. The longest wavelengths have the lowest frequencies and the lowest temperatures. The shortest wavelengths have the highest frequencies and the highest temperatures.
White light is a combination of electromagnetic waves with frequencies from what?
the range of visible light.
What is extremely low frequency radiation?
Low frequency waves are waves with long wavelengths, by definition, since their cycle is slowly repeated. One example is AM radio waves compared to visible light waves. AM radio waves have a frequency of around 1 MegaHertz (1,000,000 s-1) and are around 500 meters long. In contrast, visible light waves have a frequency of around 500 TeraHertz (300,000,000,000,000 s-1) and are around 500 nanometers long (.000000500 meters).
What do light waves of greater frequency have?
The meaning of a high frequency wave is a shorter wavelength.For electromagnetic waves in general (including light):* At greater frequencies, you get shorter wavelengths.* At greater frequencies, you get more energy per photon.
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 effect does changing the frequency have on light waves?
Different frequencies of light are different colors.

White light is made up of waves having different?
frequencies and wavelengths
Are there waves of light and sound?
Yes. Sound waves have different frequencies which cause them to be louder/softer/higher/lower.Light waves have different frequencies too. The shorter the distance between the wavelenghts the darker the color. White light (the normal light the sun gives) is all of the colors together
If colors have different wavelengths do they have different frequencies and temperatures?
Yes, light is electromagnetic waves. The longest wavelengths have the lowest frequencies and the lowest temperatures. The shortest wavelengths have the highest frequencies and the highest temperatures.
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 difference between the waves that make up bright green light and dim red light?
The frequencies and wavelenghts are different.
Since the different kinds of waves have different lengths they also have different?
frequencies.
Is speed related to the color of a light wave?
No. All colors of light travel at the same speed in vacuum. Different colors represent light waves with different wavelengths (frequencies).
What is electromagnetic spectrume?
ALL the radiation from the lowest frequency to the highest.
Do colour in visible white light have different wave lenghts and frequencies and how different are they?
yes- red has the longest waves while violet has the shortest.
