Question # 1

Define error and uncertainty ? Discuss the various types of error ?

Ans 1: Error:The difference between measured value and actual value is known as error.
Uncertainty:The errors which a rises due to natural imperfection of the experimenter the limitation of the apparatus and the change in the environment during the measurement is known as Uncertainty
Types of Errors:There are three type of errors which are given below.
1. Personal Error:The error due to carelessness or improper knowledge about an instrument or incorrect reading of a scale by an experimenter is known as personal error. The personal error can be removed to some extent error if the experimenter take care during the measurement of any quantity and have proper knowledge about the measuring instrument.
2. Systematic Error:The error due to faulty apparatus and poor calibration of the instrument is known as systematic error. The systematic error also a rises from zero error between scales as in vernier caliper screw gauge and spherometer. The systematic error can be removed by comparing the faulty instrument with some accurate and standard instrument. the difference of the two can be added tracted to the measurement if the error is positive then will be subtracted from faulty instrument reading for correctness. If the error is negative, then it will be added to the foulty instruments reading for correctness
3. Statistical Error:The error due to repeated measurements of same quantity under same condition that result in different values of the same quantity is known random error.

Question # 1

Define light year. How many meters are there in one light year?
[ Speed of light = 3x10⁸ms^-1)

Ans 1: Alight year is the distance light travels in one year.
Since
S = vt
or S = vt
S= (3x10⁸ms^-1)(365x24x60x60 s)
S= 9.46x 10¹⁵m

Question # 1

Define Base, Derived, supplementary, Units ?

Ans 1: Base Units:The units of base quantities are known as base unit.
Base quantity: Symbol
Length l
Mass M
Time t
Electric current I
Temperature T
Derived Quantity:The unit of derived quantities are known as derived units. The derived units can be derived from base unit and supplementary units
Supplementary Units:The general conference on weight and measures has not yet classified certain units of the SI under either base units or derived units such SI Units are called supplementary units This class contains only two units of purely geometrical quantities which are place angle and the said angle.
1. Radian :It is the unit of plane angle. One radian represents a plane angle subtended at the center of a circle by on are of length equal to radius of the circle.
2. Steradian:Steradian is the unit for a solid angle in a three dimensional space steradian is defined as "the solid angle subtended at the center of a sphere by an area of its surface equal to the square of the radius of that sphere"

Question # 1

Define the term error, uncertainty precision and accuracy in measurements?

Ans 1: Errors:The difference between measured value and actual value of a quantity is known as Error.
Uncertainty:An estimate of the possible range of an error is known as uncertainty. (OR)
The error which arises due to natural imperfections of the experimenter, the limitations of the apparatus and the changes in the environment during the measurement is known as uncertainty.
Precision:The measure of the consistency of measurements is known as precision. It requirements the magnitude of error in measurements.
Accuracy:The measure of correctness of a measurements is known as accuracy"
The Accuracy means to check how the measure values is closer to the actual value It is a relative is closer to the actual value.It is a relative error. it can be obtained by dividing the error with measured quantity The accuracy depends on the error is greater than smaller will be the accuracy of the measurement can be increased by taking several reading and then take their average
