What is wavelength of 518 nanometers?
The wavelength IS 518 nanometers.... but in meters, it is expressed as 5.18 x 10-7 m. when you multiply by the conversion factor of 10-9
Which electromagnetic wave has frequency of 6 X 100000000 megahertz?
A frequency of 600000000MHz is better expressed as 600THz (TeraHertz). It has a wavelength of 500 nm (nanometres) which places it in the visible spectrum. This particular wavelength is somewhere in the green. Green light is from 495 to 570 nm.
What does the increase in wavelength of light from a galaxy mean?
This is usually expressed, equivalently, as a reduction in frequency. It means that the galaxy moves away from us. For more information, you may want to read about redshift.
What is the wavelength of a wave traveling at 1000 ms with a frequency of 50 Hz?
wavelength = speed / frequency Wavelength should be expressed in meters (m), speed in meters per second (m/s), and frequency in hertz (Hz). I assume by "ms" in the question you actually mean "m/s" since the former is "milliseconds" (a measure of time) and the later is "meters per second" (a measure of speed). 1000 / 50 = 20 meters
What is the unit astronomers most often use to express the wavelength of light called?
The wavelength of light is expressed in different metric subunits derived from meters. For example, radio waves are measured in meters, visible light is measured in nanometers, and gamma rays are measured in picometers.I believe that would be the nanometer. In the past, the angstrom (= 1/10 nm) has been frequently used.
What determines the height of a wave?
Make a graph above zero mark 5 points distanced 1cm each from other. mark below zero the same but with negative sign. Any wave always have a positive or a negative or together cycle. the individual is called "half cycle" and whole is called "full cycle". Now, the contact of each wave's frequency above and below the zero; this distance is called as the length of the wave. If, you are looking for how long will it travel then it depends on its wavelength. Also, a separate carrier signal is used to carry it long distance.
How the 40 meters wave length is equal to 7 mhz frequency?
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
