What is the frequency of monochromatic light of wavelength 485 mm when the speed of light is 3.00?
The answer depends on the units in which the speed of light is given as 3.00
What are the SI units for speed of light?
Wavelength is in meters, the frequency is in hertz. period is in seconds and the wave speed is in meters per second.
How much energy is associated with an infrared photon with a wavelength of 9.90?
You haven't given units for 9.90. nm, wavenumbers? metres, centimetres? E=hc/lambda, speed of light in metres, wavelength in metres
What are the equations for wavelength and frequency of light?
The speed of light is fixed and so the wavelength and the frequency of light are related like this:wavelength * frequency = speed of lightYou just have to be careful your units match up. Often wavelengths of light are listed in nanometers, or nm, while the speed of light is often given in meters per second, or m/s. Make sure everything is in terms of meters or your answer will be way off. Frequency is almost always given in terms of 1/seconds, which is also called a Hertz. See the Web Links for more information about the electromagnetic spectrum.
If the speed of a light in a vacuum is 1.5 times that of the speed of light in a given material what is the index of refraction for that material?
1.5 no units (APEX)

What are the SI units for speed of light?
Wavelength is in meters, the frequency is in hertz. period is in seconds and the wave speed is in meters per second.
The wavelength of a beam of light passing through a vacuum is 420 nanometers. What is the frequency of the light beam?
You need to divide the speed of light by the wavelength. (To have consistent units, you must first either convert the speed of light to nm/second, or convert the wavelength to meters.)
What is the SI measurement of light?
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
What is the frequency of blue light with a wavelength of 550 nanometers?
f=c/lambda frequency = 299792458 divided by wavelength The freq is in Kilohertz, and the wavelength is in meters. A nanometer is one billionth of a meter. I'll let you figure out how to move the decimals points.
What is the frequency of radiation whose wavelength is 10?
You need specify the units associated with the number 10.In any event, a very simple relationship exists between the wavelength and the frequency for all forms of electromagnetic radiation - the product of the two is equal to the speed of light. Therefore, the frequency you want to know can be determined by dividing the speed of light by the wavelength. Just be sure that you are consistent with the units
What wavelength of light would you report in units of nm if the light had a wavelength of 7.60 x 10-10 m?
The wavelength of light, 7.60 x 10^-10 m, would be reported as 760 nm in units of nanometers.
How much energy is associated with an infrared photon with a wavelength of 9.90?
You haven't given units for 9.90. nm, wavenumbers? metres, centimetres? E=hc/lambda, speed of light in metres, wavelength in metres
What is the product of wavelength and frequency always equal to?
The product of wavelength and frequency is equal to the propagation speed of the wave. For light waves, this is the speed of light. cw: Wavelength = W meters, Frequency = F per meter W meter X F per meter = dimensionless quantity. The speed of light, c, is typically measured in units of m/s or 3(10^8) m/s. OK, some use a dimensionless speed of light, where c=1. But I don't see how that follows from the general question.
A wave has a frequency of 5 Hz and a wave speed of 18 ms. What is its wavelength?
Just divide the speed by the frequency. Since SI units are used, the wavelength will be in meters.
What is the frequency of an EM wave that has a wavelength of 1 mm?
The frequency of an electromagnetic wave with a wavelength of 1 mm is 300 GHz. This is calculated using the formula: frequency = speed of light / wavelength. Substituting the values in gives us 300 GHz.
What is the speed of a shade of yellow light with a wavelenght of 5.8x10-7 m and a frequency of 5.17x 1014 hz?
Speed is synonymous to velocity. velocity can have the units m/s. Wavelength is in "m" and frequency has units of "hz". 1 Hz is the same as saying 1 per second. So, Hz = 1/s. If you multiply your two variables, you will end up with units of m/s. Again, m/s is velocity, which is speed. The math is easy, but understanding the equations is tricky. The answer is (5.8x10^-7m) x (5.17x10^14 hz)
