Physics: An experiment is designed to measure the speed of light in a vacuum. The accepted value for this speed is 2.997 x 108 m/s. What is the percent error if the measured value of the speed of light in a vacuum as 2.783 x 108 m/s

An experimental error is a deviation from the measured value of a physical quantity with respect to the real value of said quantity. In general, experimental errors are unavoidable and basically depend on the procedure chosen and the technology available to perform the measurement. Mathematically is written as,

$\% \text{Error} = \frac{\text{Accepted Value}-\text{Measured Value}}{\text{Accepted Value}}\times 100$

Replacing with our values

$\% \text{Error} = \frac{2.997*10^8-2.783*10^8}{2.997*10^8}\times 100$

$\% \text{Error} = 4.77\%$

THerefore the value of the percent error is 4.77%

Physics

Percent error = 7.14%

Explanation:

Percentage error is the measurement of deviation between two values - measured value and known(or accepted) value - of a quantity. In the question, the quantity is the speed of light in a vacuum.

Percentage error or percent error is found by

i. finding the difference between a measured value and a known (or accepted) value,

ii. dividing the result from (i) by the known value (accepted value),

iii. multiplying the result from (ii) by 100%

iv. finding the absolute value of the result in (iii).

i.e

Percentage error = | $\frac{measured value - accepted value}{accepted value}$ | x 100%
