Question

what is LMCM' Measure in concave mirror​

Answer 1

Answer:

Mean value of the focal lenght

f

mean

=

6

17.3+17.8+18.3+18.2+17.9+18

= 17.9

Mean absolute error is

Δf

mean

=

6

∣17.9−17.3∣+∣17.9−17.8∣+17.9−18.3∣+∣17.9−18.2∣+∣17.9−17.9∣+∣17.9−18∣

=

6

0.6+0.2+0.4+0.3+0+0.1

= 0.27

Relative error is =

f

mean

Δf

mean

=

17.9

0.27

= 0.02

percentage error = Relative error ×1000

= 0.02 ×100

= 2
