1.	In an experiment the valno of refractive index of glass was found to be 1.54, 1.53, 1.44,1.54, 1.56 and 1.45 m in successive measurement. Calculate (i) the mean vlaue of refractive index (ii) absolute error of each measurement (iii) mean absolute error (iv) relative error and (v) percentage error.
Answer» SOLUTION :FREQUENCY `=100//25=4.0` OSCILLATIONS/ SECOND.
