Want this question answered?
Frequency is equal to constant divided by wavelength. 3.00x108 / 780nm equals approximately 4397435897.4359 hertz.
A ruby laser is a red laser with a wavelength between 694 nm and 628 nm. 1 nanometer = 1×10−9 meter.
Physically, light of different colors differs:* In their wavelength * In their frequency (note: the longer the wavelength, the lower is the frequency - so, they are inversely proportional) * In the energy per particle (photon) - proportional to the frequency
The frequency ranges between 450 THz and 950 THz.
The wavelength is 671 nm.
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..

nm means nanometer, that being the wavelength of that laser.
X rays have a wavelength of 4.2 nm.
DVD is an optical disk storage media format.it uses 650 nm wavelength laser diode light as opposed to 780 nm for CD and 405nm for blue-ray disc.
The frequency ranges between 450 THz and 950 THz.
The wavelength is 671 nm.
The wavelength is 671 nm.
