And 'E' ranges from 0 to eV. This explains the origin of continuous X-ra..

X-Rays follow a rectilinear propagation and travel with a velocity of 3 x 10 8 ms - 1 in vacuum. They are not deflected by electric and magnetic field. Since they do not contain any charge but are diffracted by crystals, X-rays cause fluorescence when incident on ce..

Relative error in an is n times the relative error a It can be proved that maximum relative error in X, Also, maximum percentage error in X, Maximum percentage error in X = l times maximum percentage error in a + m times maximum percentage error in b + n times..

X is the sum of 2 observed quantities a and b. X = a + b Maximum absolute error in X = Maximum absolute error in a + Maximum absolute error i..

Physical Meaning of Angular Momentum - Consider a particle capable of rotation about an axis. At any time t, let its momentum be and , the position vector. Then the angular momentum is given by the cross product and . = x..

Suppose X = a - b Let D a and D b be absolute errors in measurements of quantities a and b, values of a and b and D X be maximum error in X. Maximum absolute error in X = Maximum absolute error in a + Maximum absolute error in b From equations (1) and..
