<h2>
Answer: 745.59 nm</h2>
Explanation:
The diffraction angles when we have a slit divided into parts are obtained by the following equation:
(1)
Where:
is the width of the slit
is the wavelength of the light
is an integer different from zero
Now, the first-order diffraction angle is given when , hence equation (1) becomes:
(2)
We know:
In addition we are told the diffraction grating has 750 slits per mm, this means:
Solving (2) with the known values we will find :
(3)
(4)
Knowing :
>>>This is the wavelength of the light, wich corresponds to red.
Answer:
55407
Explanation:
we have given that magnetic field B=3.5 T
current through the coil=90 A
Length of solenoid =0.72 m
we know the formula of magnetic field
so
so the number of turn in solenoid will be 55407
