Three complete orders on each side of the m=0 order can be produced in addition to the m=0 order.
The ruling separation is d=1/(470mm-1)
Diffraction lines occurs at an angle θ such that dsin=mλ,when λ is the wavelength and m is an integer.
Notice that for a given order,the line associated with a long wavelength is produced at a greater angle than the line associated with shorter wavelength.
we take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.
That is,find the greater integer value of m for which mλ<d.
since,d/λ
There are three complete orders on each side of the m=0 order.
The second and third orders overlap.

This is called vaporization.
hope this helps :)
the answer is c because it has the most volts
a
The magnetic force on a current-carrying wire due to a magnetic field is given by
where
I is the current
L the wire length
B the magnetic field strength
In our problem, L=1.0 m,
and
, so we can re-arrange the formula to find the current in the wire:
The answer to question one is A.
The answer to question two is A.
The answer to question three is D.
