Question

In Part 3.2.2 of the experiment, a pair of students measure θmirror = 19.5 degrees. To find θbench, they use the theoretical relationship θmirror = 1/2 θbench. Then they measure θbench = 46.5 degrees. What is the discrepancy between theory and experiment for θbench?

Answer 1

discrepancy between theory and experiment 19.23 %

Step-by-step explanation:

given data

Experimental theta (E) = 46.5 degrees

and

Theoretical theta (T) = 2 × 19.5 = 39 degree

so we can say % discrepancy will be

% discrepancy =
`(E-T)/(T) * 100` .....................1

so

% discrepancy =
`(46.5-39)/(39) * 100`

% discrepancy =
`(7.5)/(39) * 100`

% discrepancy = 19.23 %

so discrepancy between theory and experiment 19.23 %
