You want to photograph a circular diffraction pattern whose central maximum has a diameter of 1.2cm . You have a helium-neon laser (λ=633nm) and a 0.13-mm-diameter pinhole. How far behind the pinhole should you place the viewing screen?
Homework Equations
Y = λx/b
Y=radius of central maximum
b= slit diameter
x=distance from screen
The Attempt at a Solution
.012/2=633e-9*x/0.00013
x=1.23m <--- This answer is wrong. I don't know why.
A 1.2cm circular diffraction pattern is a phenomenon that occurs when light is passed through a small circular aperture, causing the light waves to diffract and form a pattern of concentric circles on a screen or surface. This is a common occurrence in optics and can be observed in various experiments and real-life situations.
The distance for a 1.2cm circular diffraction pattern can be calculated using the formula d = λD/2a, where d is the distance between the center of the pattern and the first dark ring, λ is the wavelength of the light, D is the distance between the aperture and the screen, and a is the diameter of the aperture.
The distance for a 1.2cm circular diffraction pattern can be affected by several factors such as the wavelength of the light, the size of the aperture, and the distance between the aperture and the screen. Other factors that can influence the pattern include the intensity and polarization of the light, as well as any obstructions in the path of the light.
The distance for a 1.2cm circular diffraction pattern is important in scientific research because it can provide valuable information about the properties of light and the characteristics of the aperture. It is also a useful tool for measuring small distances and can be used in various experiments and applications in fields such as optics, astronomy, and microscopy.
Yes, the distance for a 1.2cm circular diffraction pattern can be manipulated by changing the variables in the formula (d = λD/2a) such as the wavelength of the light, the size of the aperture, and the distance between the aperture and the screen. However, the overall pattern and characteristics of the diffraction pattern will still remain the same.
