Explain giving examples the errors that occur while making measurements
Answers
Answer:
The errors in measurement can be classified into:
1. Systematic errors.
2. Random errors.
Systematic Errors:
**********************
systematic errors occur due to
--> Instrumentation error : For example Error might occur due to wrong construction of apparatus.
--->Environmental factor errors: For example due to presence of humidity, temperature or external magnetic field, the values may differ.
--> Observation error: For example we do wrong observation or take wrong reading which is called as Parallax error.
--> Theoretical Errors: Occurs due to simplification of theoretical system for example theory says that After performing the experiment, temperature of object does not change and we get the reading as temperature changes.
Random Errors :
A sudden change in experimental conditions noise or tiredness in working person.
For example sudden changes in weather changes( like temperature, humidity) may effect reading that we observe.
