Answer:
yes. why do you need this answered asap? lol
I believe it is Acoustics, the real name for it would be like Reverberation. But go with Acoustics. :)
The term for the process by which a portion of a glacier breaks off and falls into the water is called calving.
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)
![= 2.1 \times 10 {}^{ - 3}mm](https://tex.z-dn.net/?f=%20%3D%202.1%20%5Ctimes%2010%20%7B%7D%5E%7B%20-%203%7Dmm%20)
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
![= 538 \times 10 {}^{ - 9} m/2.1 \times 10 {}^{ - 6}](https://tex.z-dn.net/?f=%20%3D%20538%20%5Ctimes%2010%20%7B%7D%5E%7B%20-%209%7D%20m%2F2.1%20%5Ctimes%2010%20%7B%7D%5E%7B%20-%206%7D%20)
There are three complete orders on each side of the m=0 order.
The second and third orders overlap.
