There are 6.5 x 10^24 nanometers in 650 terameters.
One nanometer is equivalent to .000000001 meters (1 x 10^-9 m). Therefore 650 nanometers equals .00000065 meters or 6.5 x 10^-7 meters.
6.5 x 102
The wavelength of the water wave that measures 2 meters is 3,076,923 times bigger than the wavelength of red light that is 650 nanometers.
A tetrameter is not a unit of length - it is a unit of rhythm. Perhaps you are mistaking this for a terameter, which indeed is a unit of length, equal to 1,000,000,000 metres.
"nanometer" or billionths of a meter. 650 nanometers is the wavelength of the light produced by the diode.
The scientific notation of 65,000 is 6.5x104.
650 ÷ 10 = 65
650 billion of them.
75 is 11.54% of 650.
650 cm = 255.905"
650 kg is equal to 650,000 grams.
