The discussion revolves around calculating the width of a single slit based on the characteristics of its diffraction pattern, specifically focusing on the width of the central bright fringe and the wavelength of light used.
The discussion is active, with participants providing guidance on how to express certain variables and clarifying the use of specific equations. There is an ongoing exploration of the correct interpretation of the parameters involved in the diffraction equation.
Participants note potential confusion regarding the definitions of variables in the context of the diffraction pattern and the specific measurements being used. There is also a mention of a resource for further reading on the topic.
Yes, and for small angles tanθ ≈ sinθ.phy112 said:is it the eq. tantheta=h/D?
Not exactly. Note that in the diffraction equation, "h" is measured from the central maximum.phy112 said:do you use h=1.9 cm and D=1.05m?
