Actually, if that is all that is provided in the question it is safe to assume it is through a vacuum, where the speed of all electromagnetic waves is identical. Through a vacuum, the speed of light is 3*10^8 metres per second

If the wavelength of a red light is 650 nanometers How much bigger is the wavelength of a water wave that measures 2 meters?

650 nm= .00000065 m 2m - .00000065m= the water wave is ~1.99999935 meters larger than the red light wave


The wavelength of microwave radiation is the wavelength of visible light?

Not even close. Microwaves are much longer, with a lower frequency, than light is.The shortest 'microwave' is in the neighborhood of 1 millimeter long (300 GHz).That's about 1,540 times as long as the longest visible wave (red, 650 nm)).


What wave lengths are the colors in the spectrum?

The visible violet light has a wavelength of about 400 nm. The visible indigo light has a wavelength of about 445 nm.The visible blue light has a wavelength of about 475 nm.The visible green light has a wavelength of about 510 nm.The visible yellow light has a wavelength of about 570 nm.The visible orange light has a wavelength of about 590 nm.The visible red light has a wavelength of about 650 nm.


What is a 650nm laser beam?

650 nm is the wavelength of the light. The wavelength determines the color. 650nm light is red.


What is the wavelenth of red laser light?

visible red light has a wavelength of about 650 nm


What is the light waves of light?

Light waves pertain to the frequency of light. All light is known as electromagnetic radiation and travels in the form of a wave (although it does have particle characteristic) meaning that these waves have different frequencies. A frequency tells us how often the waves goes up and down and how powerful they are. Light can also be measured by it's wave length, the distance it take for the light to go up and back down again (vice versa). A certain wavelength of light will be a different color, for example if light (Electromagnetic Radiation) has a wavelength of 650 nm (nanometers) then it will appear as the color red. Humans can only perceive light that has a wavelength in between 350 nm and 750 nm, a very small portion of all electromagnetic radiation. Here is a list of colors pertaining to their wavelength: Violet: 400 nm Indigo: 445 nm Blue: 475 nm Green: 510 nm Yellow: 570 nm Orange: 590 nm Red: 650 nm White: White is a mixture of all colors of visible light. Black: Black is an absence of light, meaning that there is no light.


Why does red have a lower frequency then other colors?

The naming of the colours in the visible spectrum were arbitrary, However there was a common agreement that red (or equivalent terms in other languages) was the colour associate with light having a wavelength of about 650 nm. This wavelength is longer than the other visible light colours and is part of the overall electromagnetic spectrum ranging from wavelengths of a millionth of a nanometer (gamma rays) to radio wave of a 100 km or so.In short the name came first, then we figured out what the wavelength was.


How does wave length affect visible light?

It affects the color of the light. If you change the wavelength of visible light, you change the light's color. For instance. Red is a wavelength of approximately 650 nanometers. Orange, about 590. Yellow, 570. Green- 510, Blue, 475 nanometers. Indigo is 445 and Violet is about 400. You can see more here: http://eosweb.larc.nasa.gov/EDDOCS/Wavelengths_for_Colors.html#red


What does the nm in 650nm laser diode mean?

"nanometer" or billionths of a meter. 650 nanometers is the wavelength of the light produced by the diode.


The wavelength of red light is 650 nanometers. How much bigger is the wavelength of a water wave that measures 2 meters?

Assuming you want the ratio:The prefix "nano" means ten to the power -9, so you need to divide 2 by (650 x 10 to the power -9). In Excel, you can use this formula: =2/650e-9


What color is the laser beam in a DVD drive?

Red - its 650 nanometer wavelength puts it squarely in the middle of the visible light's red spectrum.


What is the energy of orange light that has a wavelength of 650 nm?

We start with two formulas; E = hf and f = c/λwhere:E = Energy (eV)h = Planck's Constant (6.626x10-34 (J-s))f = frequency (Hz) of orange light at 650 nmc = speed of light (3x108 m/s)λ = wavelength of orange light (nm)First, f = c/λ can be used to replace f in E=hf making the revised formula E = hc/λ;Solve for E;E = (6.626x10-34 * 3x108 ) / 650x10-9 = 3.0582x10-19 eV
