Question

Помогите, пожалуйста решить. На дифракционную решетку падает нормально монохроматический свет. В спектре некоторая спектральная линия наблюдается во втором порядке под углом 30°. Наивысший порядок спектра, в котором может наблюдаться эта линия, равен

Answer 1

Дано    k1=2   ф1=30     k- ?

для 1 случая   d*sina1=k1*л
для 2 случая   d*sina=k*л
k=kmaх если sina=1  
kmaх/k1=1/0,5=2
kmaх=2*2=4

Diffraction Grating and Spectral Lines

When a monochromatic light falls normally on a diffraction grating, it produces a pattern of diffracted light known as a spectrum. The spectrum consists of multiple spectral lines, each corresponding to a different wavelength of light. The diffraction grating is a device with many closely spaced parallel slits or grooves that cause the incident light to diffract and interfere with each other, resulting in the formation of the spectrum.

In this case, a specific spectral line is observed in the second order at an angle of 30°. The second order refers to the second bright spot or maximum intensity observed in the diffracted pattern. The angle of 30° indicates the deviation of the diffracted light from its original path.

To determine the highest order of the spectrum in which this particular spectral line can be observed, we need to consider the relationship between the angle of diffraction, the order of the spectrum, and the wavelength of light.

Relationship between Angle of Diffraction, Order, and Wavelength

The relationship between the angle of diffraction (θ), the order of the spectrum (m), and the wavelength of light (λ) can be described by the equation:

m * λ = d * sin(θ)

Where: - m is the order of the spectrum - λ is the wavelength of light - d is the spacing between the slits or grooves of the diffraction grating

In this case, we know that the angle of diffraction (θ) is 30° and we want to find the highest order of the spectrum (m) in which the spectral line can be observed.

To find the highest order (m), we need to know the wavelength of the spectral line or the spacing between the slits or grooves of the diffraction grating. Unfortunately, the provided search result snippet does not provide the necessary information to calculate the highest order.

To solve this problem, we need additional information such as the wavelength of the spectral line or the spacing between the slits or grooves of the diffraction grating. With that information, we can use the equation mentioned above to calculate the highest order of the spectrum in which the spectral line can be observed.

If you have any additional information or if there's anything else I can help you with, please let me know!
