Displacement: - The modification in position of a body in a particular direction is called as displacement. It is a vector function and its unit in SI system is meter.
Distance: The actual length of path traversed by a body in a sub interval of time is known as distance. It is the actual path travelled by an object between its final and initial positions. It is a scalar function and its unit in SI is meter. Displacement can be positive, zero or negative but distance is always positive. If a particle goes in a straight line without modification in its direction, the value of displacement is same to the distance travelled. Otherwise it is usually less than it. Thus, Displacement distance

Write down the relation between focal length and power of a lens. Write down the expression for the equivalent focal length of two thin lenses separated by a distance.
Explain the presence of unmodified radiation in Compton scattering.
a) Amplitude : It is the main value of distance of the particle from its equilibrium position. b) Time period (T): Smallest time interval after which the oscillatory motion
