The frequency is 
and it is blue light
Explanation:
The relationship between the speed, the frequency and the wavelength of an electromagnetic wave is given by:
where
is the speed of light
f is the frequency of the wave
is its wavelength
In this problem, the wavelength of the wave is
Therefore, its frequency is:
The wavelength of this wave is
And by looking at the table of the wavelengths of the colors, we notice that this corresponds to the blue light, which has a range of wavelength of
[450 - 495] nm

Answer:
a fish cannot be killed by throwing an arrow into the water because you have to throw the arrow at the fish not just in the water….
Explanation:
common sense TwT
duhhh
Large glowing balls of plasma held together by their own gravity are called stars
The first telescopes were refracting telescopes ... a tube
with lenses at both ends. The quality of the image depends
on the quality of both lenses, because the light must pass
through both of them.
The reflecting telescope was an improvement, because the
light doesn't have to go through the mirror. The quality of the
primary mirror only depends on the shape and shinyness of
its surface.
If you could carve an optically perfect parabolic surface out of
a piece of wood and coat it with a thin layer of shiny silver, then
you could use a log to make a good reflecting telescope.
II seem to recall that Newton made one out of brass !
It means to brake up like
HA-H+ + A-
THE H+ IS the acid hydrogen while the A- is rest of the acid
