LAB REPORT FOR MP3 EXPERIMENT: Geometrical Optics Section VI VI 2(a) Thickness of glass plate “d” = 0.6cm R dark circle = 0.9cm Using the equation ” we can find refractive index “ n ” of the glass plate. Thus, n = 1.61 VI 3(a) F LENS = 127mm o(mm ) 180 190 200 210 220 230 240 250 260 270 280 290 i(mm) 534 445 392 347 324 301 283 269 254 246 240 228 Plot of 1/i VS 1/o Using the equation, , “f” = 28.31 Intercept using above equation = 0.00766

Here, from graph Slope = -0.85 Intercept = 0.007188752 Percentage error of intercept is 6.61% Uncertainty of intercept = 3.62007 x 10^-05 VI 3(b) F LENS = 48mm o(mm) I(mm) L(length f the object)(mm) L’(length f the image)(mm) 100 88 10 10 Now |M|= i/o , M from above table = 88/100 = 0.88 M from experimental values (taking last values) = 0.78

Unformatted text preview: There is not much difference between the calculated and experimental values of M, only difference of “0.02”. VI 4 Here ‘ f’ = 25mm, for concave mirror. Image distance (M=1): 51mm Thus, using o=2 f We get ‘ f’ = 25.5mm Therefore, percentage error in determining focal length of curved mirror is 2%.
