Answer:
The minimum value of width for first minima is λ
The minimum value of width for 50 minima is 50λ
The minimum value of width for 1000 minima is 1000λ
Explanation:
Given that,
Wavelength = λ
For D to be small,
We need to calculate the minimum width
Using formula of minimum width
![D\sin\theta=n\lambda](https://tex.z-dn.net/?f=D%5Csin%5Ctheta%3Dn%5Clambda)
![D=\dfrac{n\lambda}{\sin\theta}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7Bn%5Clambda%7D%7B%5Csin%5Ctheta%7D)
Where, D = width of slit
= wavelength
Put the value into the formula
![D=\dfrac{n\lambda}{\sin\theta}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7Bn%5Clambda%7D%7B%5Csin%5Ctheta%7D)
Here,
should be maximum.
So. maximum value of
is 1
Put the value into the formula
![D=\dfrac{1\times\lambda}{1}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7B1%5Ctimes%5Clambda%7D%7B1%7D)
![D=\lambda](https://tex.z-dn.net/?f=D%3D%5Clambda)
(b). If the minimum number is 50
Then, the width is
![D=\dfrac{50\times\lambda}{1}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7B50%5Ctimes%5Clambda%7D%7B1%7D)
![D=50\lambda](https://tex.z-dn.net/?f=D%3D50%5Clambda)
(c). If the minimum number is 1000
Then, the width is
![D=\dfrac{1000\times\lambda}{1}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7B1000%5Ctimes%5Clambda%7D%7B1%7D)
![D=1000\lambda](https://tex.z-dn.net/?f=D%3D1000%5Clambda)
Hence, The minimum value of width for first minima is λ
The minimum value of width for 50 minima is 50λ
The minimum value of width for 1000 minima is 1000λ
Answer:
Explanation:
There are different theories and evidence about the big bang, in this case, we're going to see three evidence.
The galaxies are moving from us, this means space is expanded, this in consequence Big Bang's explosion.
The cosmic microwave background radiation is related to the early warmth of the universe.
The observed abundance of hydrogen, helium, deuterium, lithium, these are checked from the spectra of the oldest stars.
Answer: It is the same amount of weight as the girl is putting on the pogo stick. When you are pushing something downward then gravity will push back with the equal amount of force.
Explanation:
The answer for that questions will be 759. Stars itir
That's good ! I never heard of that before. (Maybe because
I've never been stung by an ant.)
When an ant bites or stings, it injects a tiny amount of 'formic acid'
into your skin. Soon, the formic acid itches, burns, and stings, and
after a while, a little piece of skin dies and falls off. Some people
are seriously allergic to it, and it can make them really sick.
'Acids' and 'bases' are opposites, and one can neutralize (cancel out)
the other. Tony is putting a weak 'base' on the sting, to neutralize the
formic acid that the ant left him as a little gift.
