What type of visible light is the sun?
The sun emits all colors of visible light, including red, orange, yellow, green, blue, and purple. The sun's surface temperature is 5,800 Kelvin, and its sunlight has a peak wavelength of about 550 nanometers. This wavelength is perceived as visible white light
How are rainbows formed after raining?
Light travels in waves. The light's wavelength determines its perceived color. Short wavelength light, for example, appears blue, and long wavelength light appears red. Sunlight is composed of light of many wavelengths. In the range that we can see, this includes the colors of the rainbow. When light enters water it bends (refracts). The amount of bending depends on the wavelength of light. As a result, the light splits into its component colors.the water / fog in the air reflects the sunlight, causing the white light of the sun to divide and become a rainbow color in the sky
Why is called as monocromatic source of light?
Mono chromatic light is emitted by a laser source or by a red Light Emitting Diode. These sources emit a single wavelength of light around 550 nanoMetres. White light from the sun for example is a mixture of many wavelengths mixed together from red to violet to form white light.
Is sun light a monochromatic light?
No. White light is a mixture of different colors.
Why is the sunrise orange or white?
At lower altitudes and low sun (dawn/dusk) the sunlight has to shine through more atmosphere. The Sun emits electromagnetic radiation, of which white light is a part. White light can be split into the colours of the rainbow. The Blue end of the spectrum is the shorter wavelength, and the Red end is the longer wavelength. The shorter/longer the wavelength the less/more penetrating they are. e.g. you cannot see light/uv rays (shortwavelength) through a brick wall, but you can feel IR(heat)( longwavelength) through a brick wall. So the longer wavelengths from the Sun (yellow/orange/red) will penetrate further through the atmosphere. Hence you see this colour light with a setting/rising Sun. Contrast this , when the Sun is high in the sky (midday) sunlight has less atmosphere to penetrate through, so it follows that the shorter wavelengths can pass through and the light changes to white. Do not confuse this with 'Blue Sky' that is a different phenomenon.
Why white light of sun cannot considered pure and uniform?
The white light of the sun cannot be considered pure and uniform because they have different wavelength in different times.
What type of visible light is the sun?
The sun emits all colors of visible light, including red, orange, yellow, green, blue, and purple. The sun's surface temperature is 5,800 Kelvin, and its sunlight has a peak wavelength of about 550 nanometers. This wavelength is perceived as visible white light
What is the wave length of the light used newtons ring?
Any wavelength of light can be used. Natural light, the white light we receive from the Sun, is a mixture of waves with wavelengths between about 350 and 700 nm.
Why does the sun produce light of that wavelength?
Because that's what the chemical reactions going in in the sun does.
How measure the sun temperature?
Use a spectrometer to measure the wavelength of the light. There is a direct, but inverse correlation of the wavelength to the temperature.
What colors are associated with wavelength?
Of the colors visible to humans, red light has the lowest wavelength. Violet light and white light have the highest wavelengths.
Why does a white piece of paper appear white in white light red in red light blue in blue light and so on?
White surface reflects all wavelengths of visible light spectrum (ie. white color is a mixture of all the other colors). If the light that falls on the surface has one specific wavelength, only that wavelength occurs in the light reflected.

What is the difference between yellow light and white light?
White light is a mixture of all the wavelengths of the visible spectrum. Visible light ranges from approximately 400 to 800 nm in wavelength. Wavelength of yellow light is565-590 nm.We perceive electromagnetic radiation with a wavelength between 565 and 590 x 10-9 m as yellow light.
Why moon is giving white light though it is reflecting sun's energy?
Because the sun's light is white light as well.
When is a rainbow formed?
They are formed when it is raining outside and there is also sunlight. White light from the sun does not have 1 specific wavelength. It's like asking what is the average height of 5 brothers. All colours have different wavelengths. When white light is refracted from a water particle. Every colour has a different wavelength. Blue is the shortest and red is the longest. Therefore blue takes more time to cross the water particle then the red wavelength. In fact, all wavelengths from the sun light cross the water particle at different times. This creates a diffraction pattern that is always the same… a rainbow.
