400 nanometers = 4.0 × 10-10 kilometers
149,000,000 kilometers is 149,000,000,000,000,000,000 nanometers.
5 nanometers converts to 0.000000000005km
That's impossible to say with the information provided in the question; Hertz is cycles per second and nanometers is a measure of length...
There are 40,000,000 centimeters in 400 kilometers, as there are 100,000 centimeters in a kilometer.
it is not knowlageable to me
The wavelength of an ultraviolet wave typically ranges from about 10 nanometers to 400 nanometers. This places ultraviolet waves just outside the visible light spectrum, which generally ranges from 400 to 700 nanometers.
The wavelength of light (400-700).
400 kilometers = 248.55 miles.
400/6=66,66
The wave frequency for 400 nanometers is approximately 750 terahertz (THz). This can be calculated using the formula: frequency = speed of light / wavelength.
About 400.
Most humans eyes are sensitive to wavelengths between about 400 nanometers and 700 nanometers
