Electric fields
Ok thanks that's cleared things up somewhat.
Does this mean that an electric field would be refracted upon going from say air into water?
Wkipedia gives refractive index
n^2 = (Relative Permittivity) x (Relative Permeability)
but taking water as an example
n = 1.33
Relative Permeability = 1.0 (roughly)
Relative Permittivity = 80.4
1.33^2 = 1.77 Which is NOT 80.4
what's wrong?
Question goes as follows:
"In an ionised gas there are positive ions and electrones moving around in collision with molecules of the gas. Calculate the ratio of the mean free path of the electrons in the gas to the mean free path of the positive ions in the gas."
As far as I can see I...
well whatever you do get rid of "the bbc space series with sam neil" its complete rubbish, it's one of these science programmes that spend a lot of time telling you a load of nothing. They simply dazzle you with pretty pictures to convince you that you're learning something.
[FONT=Times New Roman]Hello there, unusual question but can anyone think of some good physics related foods?
for example:
an apple (Newton)
a pie (3.14...)
Milky Way/Galaxy/Mars bars
:-p you get the idea :-p
Zapper - Yes I should have said slit rather than grating
Dextercioby - "The wavelength is computed for each particle.Depends whether the neutrons are held together (like in a nucleus) or act as invidual particles (like ina beam)."
That's exactly what I was wondering - what counts as...
well ok, what if there were a few million neutrons held together by gravity how would you work out the wavelength?
If someone was to point to a bunch of neutrons and ask you to work out the wavelength would you calculate if for the whole bunch or for each individual neutron?
whether your...
Ok I don't have some of the exact values (such as width of a neutron etc.) but I hope you understand what I mean.
Take the two particles to be neutrons. They are not held together by any force other than gravity and are traveling through a vacuum at a constant speed relative to the...
De Broglie said that all matter is both a wave and a particle.
Davisson and Germer proved this in 1927 when they scattered electrons through a single crystal of nickel. :smile:
Electrons are currently believed to be a fundamental particle and so I can comfortably think of them as having a...
ok so assuming Oxygen in H2O2 is -1 and the hydrogen +1:
H2O2 --> H2O + O
The oxidation state of oxygen in the H20 is now -2, so would you say that one oxygen has been reduced and the other oxidised?
In a redox reaction I found, Hydrogen Peroxide (H202) was taken as having an oxidation state of zero
However my chemistry teacher keeps telling me that oxygen ALWAYS has an oxidation state of -2 so that would mean the hydrogen in H202 must have an oxidation state of +2 to keep the molecule...
