Light incident on a pair of slits produces an interference pattern on a screen 2.3 m from the slits. If the slit separation is 0.016 cm and the distance between the bright fringes in the pattern is 0.77 cm, what is the wavelength of the light?

Which equation do I use for this? Any help would be appreciated!! Thanks!

Prove than (1-cosx)/sinx is the same as tan x/2?

so far ive got:

(1-cosx)/sinx = 0

1/sinx - tanx = 0

Am i heading in the right direction?? Could anyone help me find the answer?

Thanks

I have heard varying reports as to whether microwave ovens heat from the outside in or from the inside out.
I always understood that heating from the inside is a myth. (I have certainly found that if food is not heated for a sufficient length of time, the centre can be cold whilst the edges can be hot/bubbling. Scientific answers please, rather than just opinions. Thanks

I think it does have something to do with the atomic structure, but to tell you the truth, I could not find the answer anywhere. physics Lecturers, come out and help!

Build another hexane molecule and place it alongside the first one you built.

Convert one of the terminal methylene groups (—CH3) on each molecule into a carboxyl group: (hexanoic acid (L, B)

What type of biomolecule have you created? Label the carboxylic terminal group

Orient (B) the two molecules so that portions of the molecules that would normally form intermolecular bonds lie next to each other.

Create a double bond between the third and fourth carbon atoms.

Describe the change in the overall shape of the molecule caused by the introduction of a carbon-carbon double bond

Keeping the carboxyl groups as close to one another as possible, orient the molecules parallel to each other

Construct four water molecules and place them around the organic molecules (hexanoic acid) oriented according to the type of intermolecular bonds they would form. In this drawing you will have a molecule of hexanoic acid surrounded by four water molecules

does any one have a link?

Yes, I know, they keep coming, but they've been getting harder, so. :)

So, what how do you set this problem up into two different equations?

Solve for x:

What does x by itself stand for? And -x? Do they mean 1 and -1?
