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 visible light color is strongly absorbed by chlorophyll?
Predominantly red and blue spectum, green is refelcted
Which portion of the electromagnetic spectum can be viewed with the bare human eye?
The visible light spectrum (wavelengths from 380 to 700 nanometers)
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.
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.
What electromagnetic waves can thermal cameras detect?
The infrared spectum since this is attributed to heat.
Who are Emerson foo and wong yang?
they are the people who made the electrognetic spectum song ( look it up on youtube)
Which cellphones employ Spread spectrum?
all CDMA and UMPS and HSPA phones have spread spectum applied!
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 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.
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
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.
