ANSWER

The intensity of X-rays decreases exponentially according to the law I=I0 e-kx, where I0 is the initial intensity of X-rays and I is the intensity after it penetrates a distance x through lead. If k be the absorption coefficient, then find the dimensional formula for it.

Yogita Ingle 6 years, 6 months ago

The systematic errors are those errors that tend to be in one direction, either positive or negative.
Systematic error can be categorised into:
i) Instrumental errors that arise from the errors due to imperfect design or calibration of the measuring instrument, zero error in the instrument, etc.
ii) Imperfection in experimental technique or procedure - External conditions (such as changes in temperature, humidity, wind velocity, etc.) during the experiment may systematically affect the measurement.
iii) Personal errors that arise due to an individuals bias, lack of proper setting of the apparatus or individuals carelessness in taking observations without observing proper precautions, etc.
