White light is composed of many colours. When these colours combine, they look white. One way of showing that white light is composed of different colours is to make white light pass through a glass prism. This splits up the white light into its constituent colours. I f you hold a screen in its path, you will see a band of colours. This band of colours is called the spectrum. Since it is visible to human eyes, it is called the visible spectrum.
What else can I help you with?
What is the spectum of light bent into a circle?
A spectrum of light bent into a circle would appear as a rainbow ring, with the different colors of light arranged in a circular pattern. This effect can be seen in nature, such as in a rainbow, or can be created artificially using a prism or diffraction grating.
What is a range of light frequenies you can see?
On average humans can see from about 400 to 700 which is the span of visable light on the electromagnetic spectum.
What is the difference between reflection and absorption?
Reflection is when a wave of light bounces away from the material, depending on the material it may maintain its strength. However absorbtion is when the beam of light hits a material and does not bounce back. To explain why light does not bounce back (becomes absorbed) you will need to know about the colour spectrum. A wave of white light contains, Red, Orange, Yellow, Green, Blue, Indigo and Violet. Certain coloured materials will absorb and reflect certain colours of the colour spectum. So say we aim our wave of light at a black filter. Black will absorb every colour in the colour spectum, thus not allowing for any reflection.
What properties does visible light have in common with the rest of the electromagnetic spectrum?
Visible light is a subset of the electromagnetic spectrum. Starting at the longest wavelengths (lowest frequencies), the electromagnetic spectum includes:Radio wavesMicrowavesInfra-redVisible lightUltravioletX-raysGamma raysRefer to the related link below for additional informaiton.
What is the shortest region of the electromagnetic spectum?
Visible region is the shortest region in the electromagnetic spectrum. Please see the attached picture. It is the shortest defined region. However if you mean wavelength, the further you go on the UV side, the shorter the wavelength. If you are talking about frequence, frequency and wavelength are inversely proportional, so it would be furthest to the IR side. The question is not about the shorter wavelength or less frequency. It is about the region covered in the whole spectrum. So visible with VIBGYOR having wavelength starting from 350 nm to 750 nm will be the visible region where as other regions such as UV and IR would have a larger range.
What electromagnetic waves can thermal cameras detect?
The infrared spectum since this is attributed to heat.
What visible light color is strongly absorbed by chlorophyll?
Predominantly red and blue spectum, green is refelcted
Which cellphones employ Spread spectrum?
all CDMA and UMPS and HSPA phones have spread spectum applied!
Who are Emerson foo and wong yang?
they are the people who made the electrognetic spectum song ( look it up on youtube)
What energy is a light?
light energy is any visible form of energy that forms part of the electomagnetic spectum it is therefore transmitted as any form of electromagnetic wave.
Why do you see a spectrum of colors?
we see a spectum of colours because we cant make white light that easily and we need the different colours to make white light!i hope i helped you answer the question
Which portion of the electromagnetic spectum can be viewed with the bare human eye?
The visible light spectrum (wavelengths from 380 to 700 nanometers)
How is the electromagnetic spectrum related to sight?
Visible light is a subset of the electromagnetic spectrum. Starting at the longest wavelengths (lowest frequencies), the electromagnetic spectum includes:Radio wavesMicrowavesInfra-redVisible lightUltravioletX-raysGamma raysRefer to the related link below for additional informaiton.
How many colors are in a spectum?
A spectrum contains an infinite number of colors since it is a continuous range of wavelengths of light. However, the visible spectrum typically consists of the colors of the rainbow, which are red, orange, yellow, green, blue, indigo, and violet.
Why colour rings are formed when petrol is added to water?
As petrol as a different refractive index than water so light rays crossing the petrol water surface gets refracted and reflected giving a spectum band like the ones we see in rainbows.
What is the spectum of light bent into a circle?
A spectrum of light bent into a circle would appear as a rainbow ring, with the different colors of light arranged in a circular pattern. This effect can be seen in nature, such as in a rainbow, or can be created artificially using a prism or diffraction grating.
