WebPROBLEM SET NO. 3 1. TWO PEG TEST. In the two-peg test of a dumpy level the following observations were taken: with level set up near A, observed readings are a=1.855m and b=1.434m; with level set up near B, c= 1.790m and d=2.211m. Determine the correct reading on the rod held at A with the instrument still in the same position at B for a horizontal line … WebSlot the collimating slit into the ray box and turn on, producing a narrow ray of light. 2. Place the first block of material on top of a piece of paper. Trace around the block using a pencil. 3. Draw a normal to the block (a line at 90° to the surface of the block).

Web3. dec 2024 · In this paper we propose a gold-plated photonic crystal fiber (PCF) refractive index sensor based on surface plasmon resonance (SPR), in which gold is coated on the external surface of PCF for easy fabrication and practical detection. The finite element method (FEM) is used for the performance analysis, and the numerical results show that … Web10. dec 2012 · Spatiotemporal compression of ultrashort pulses is one of the key issues of chirped pulse amplification (CPA), the most common method to achieve high intensity laser beams. Successful shaping of the temporal envelope and recombination of the spectral components of the broadband pulses need careful alignment of the stretcher-compressor … scratch cards winners left

WebLet us understand the phenomenon of refraction of light with the help of an activity. Take a white sheet and put a glass slab over the sheet. Draw the outline of the slab and mark it as ABCD as shown in the fig. Take two pins, say E and F and put them at the edge of A and B. Now, look at the images of the pins E and F through the opposite sides. WebInterference and schlieren methods are used to estimate homogeneity in refractive index. Interference methods allow one to observe and evaluate quantitatively the gradual changes in ... without strict requirements for optical working, ... interferometry is most suitable for rapid analysis of crystals before practical use. Measurements have been ...
