A crystal has an interplanar spacing of 98.2 pm. Using first order diffraction, what is the X-ray wavelength required to produce a reflection with an angle of 17.5 degrees?

Using d sin π = nπ, d=98.2pm, n=1, π=17.5ΒΊ
98.2sin(17.5ΒΊ) = 1π
π=29.53pm

What is the wavelength of a wave with a frequency of 5 Hz and a speed of 25 M's?
Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m
How does increasing the speed of a wave affect its wavelength?
Wavelength also increases proportionally. Reasoning: Relevant equation- v= f x wavelength therefore speed is directly proportional to wavelength, and so as speed increases, the wavelength would increase proportionally. hope this helps if more information is required, email me @ physicsisland@hotmail.com
Why measurement is required?
it is required to improve the efficiency of production.
What does joining period required means?
Joining Period Required?
Can the word expected the same as required?
The word "expected" is not the same as "required". Something that is "expected" is something that is assumed will occur. Something that is "required" is something that is essential.
Why is it difficult to demonstrate diffraction of light waves?
It is difficult to demonstrate diffraction of light waves because the wavelength of visible light is very small compared to everyday objects, making the effects less noticeable. Additionally, light waves diffract more prominently when encountering obstacles or slits that are comparable in size to their wavelength, which is not easily achieved with visible light. Finally, the precise conditions required for a clear demonstration of light diffraction, such as a coherent light source and appropriate diffraction grating, can be challenging to set up.
What is the term for the time required for a wavelength to pass?
the period.
Why is X-ray radiation required in protein structure determination?
X-ray radiation is used in protein structure determination because it can penetrate dense protein crystals and interact with the electron cloud surrounding atoms. When the X-rays hit the crystal, they diffract, and the resulting diffraction pattern can be used to determine the three-dimensional structure of the protein.
What is required in order for diffraction to occur?
Diffraction occurs when a wave encounters an obstacle or aperture that causes the wave to bend around it. It requires the wavelength of the wave to be on the same order of magnitude as the size of the obstacle or aperture. Additionally, diffraction is more pronounced for waves with longer wavelengths.
What is the wavelength of a wave with a frequency of 5 Hz and a speed of 25 M's?
Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m
What is threshold wavelength?
Threshold wavelength refers to the minimum wavelength of light required to start a specific phenomenon, such as photoelectric effect or emission of electrons from a metal surface. Below this threshold wavelength, the desired effect does not occur.
What is the time required for one full wavelength to pass a certain point.?
The Period

The minimum energy required to break the oxygen oxygen bond is 495 kJmol The wavelength of sunlight that can cause this bond breakage is 241nm How do you obtain this wavelength?
To find the wavelength, first convert the energy required to break the bond from kJ/mol to J/molecule. Then use this energy value to calculate the frequency of the light required using the formula E=hf, where E is the energy, h is Planck's constant, and f is the frequency. Finally, use the relationship between frequency and wavelength (c = Ξ»f) to find the wavelength, where c is the speed of light.
What is the maximum wavelength of light in nm required to ionize a single rubidium atom?
The ionization energy of a rubidium atom is about 403 nm. Therefore, the maximum wavelength of light required to ionize a single rubidium atom would be higher than 403 nm.
How do you write a reflection about a maths assigment?
reflection just means the mirror image. in the coordinate system just reflect the graph across the given axis that y ou are required.
Do personal reflection papers need references?
Personal reflection papers are typically based on your own thoughts, experiences, and insights rather than on research or external sources. As a result, references are not usually required in personal reflection papers. However, if you do reference external sources or research in your reflection, then proper citations should be included.
