The unit expressed in 660 nm of light represents the wavelength of light. If you want to determine the frequency, you use the speed of light to relate the two. The formula is:
c = λν
where
λ is the wavelength
ν is the frequency
c is the speed of light = 3×10⁸ m
Apply SI units:
(3×10⁸ m) = (660×10⁻⁹ m)(ν)
Solving for ν,
<em>ν = 4.55×10¹⁴ s⁻¹</em>
Answer:
I believe the answer is compressed
Explanation:
The answer may be a slightly different word, but if it's looked at by a human and not a robot compressed should work too
The period determines the horizontal arrangement of the periodic table, I think anyways
Nitric oxide occurs in the tropospheric nitrogen cycle, but it destroys ozone in the stratosphere. The equation for its reaction with ozone is :
NO + O3 → NO2 + O2
The equation of reverse reaction is:
NO2 + O2 → NO + O3
When Nitrogen oxide reaches the stratosphere, it breaks down to form nitrogen oxides. These reactions causes ozone-depletion. This gas has become the largest ozone destroying factor.
Nitrogen oxide is produced due to fertilizers and at sewage treatment plants. In 1980s, Man-made CFCs started to make holes on the ozone but it was banned due to the treaty of Montreal Protocol. Regular Emission of NO can cause worse situation than CFCs.
