Question

The refractive index of Glass is found to have values 1.45, 1.44, 1.54, 1.56, 1.53, 1.54 respectively. Calculate (1)mean value of refractive index, (2)mean absolute error, (3)relative error, (4) percentage relative error. Express the result in terms of absolute error and percentage error.​

Answer 1

Answer:

Explanation:

1)mean value of refractive index,

1.45+1.44+1.54+1.56+1.53+1.54/6

= 1.51

mean absolute error

= 0.06+0.07+0.03+0.05+0.02+0.03/6

= 0.043

relative error= 0.043/1.51

= 0.028

percentage relative error.

= 0.028*100

=2.8%
