Why is X-ray radiation required in protein structure determination?
Protein structure determination is basically crystallography i.e. finding out the arrangements of atoms. This technique uses Diffraction maxima and minima to determine 3D structures. For diffraction to occur, the size of the obstacle must be close to the wavelength of light used. Since the obstacles in this case are molecules, we use X rays, whose wavelength is comparable to radius of molecules.
What is required in order for diffraction to occur?
Waves have to bend around an obstacle.
What is the term for the time required for a wavelength to pass?
the period.
What is the purpose of filter in planks constant experiment?
To get the required wavelength of light
What is the time required for one wavelength to pass a certain point?
The Period
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 the time required for one full wavelength to pass a certain point?
The Period
The is the time required for one full wavelength to pass a certain point.?
The Period
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
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.
What is the speed of a water wave that has the frequency of 0.5 Hz and a wavelength of M?
Speed = frequency x wavelength So required speed = 0.5 * 1 = 0.5 m/s Problem is that the wavelength is not given, but I have taken as 1 m for granted. Hence the answer
What is the wavelength of sound waves produced by a guitar string vibrating at 440 Hz?
Wavelength = velocity of sound in the medium / frequency Here velocity is not given. Let it be 330 m/s So required wavelength = 330/440 = 3/4 = 0.75 m
