Compton Scattering

By
 Q. A photon traveling in the positive x-direction collides with a stationary free electron. The incident photon has a wavelength of 0.0310 nm. Post-collision, the electron moves at an angle 𝛼 below the positive x-axis, and the photon deflects at an angle 𝜃 = 66.3° above the positive x-axis. A) Calculate the angle 𝛼 (in degrees). B) Compute the velocity of the electron (in m/s). Solution:

Periodic Functions

                    What is a Periodic Function? If the function 𝑓(𝑥)  repeats it’s value after equal interval of x , then 𝑓(𝑥)  is said to be a periodic function of x and the equal interval of x , is known as time period of the function 𝑓(𝑥) .                                       𝑓(𝑥) = 𝑓(𝑥 + 𝑇) = 𝑓(𝑥 + 2𝑇 )=. . . . . . . . . . = 𝑓(𝑥 + 𝑛𝑇) =. . . . . Here T is known as the time period of the function. Types of Periodic Function : Sinusoidal Periodic Function:    A sinusoidal function is a function that is like a  sine or cosine  functions.  Sinusoidal functions  are a specific type of  periodic function . Period of  Sine  and Cosine is 2π.  Time Period of Sin (t) and cos (t) is  T = 2𝜋    Time Period of Sin (mt) and cos (mt) ...

Projectile Motion

Motion in Plane: Previously we discussed motion in a straight line. Motion in straight line belongs to one dimension. Thus, Motion in plane defined in two dimensions. If an object is free to move in a plane, its position can be located with two co-ordinates. Let's consider an object is situated in x-y plane. It moves along the following path- During the path object moves along X direction as well as Y direction. In time interval t to t+t 1  (here t 1  is very small time interval) object displaced x 1  and y 1  in X and Y direction  respectively . Displacement is in both X and Y direction, so there will be different velocity and acceleration in both directions. If we take u x  ,v x  ,a x  as initial velocity ,final velocity and acceleration in X direction and  u y  ,v y  ,a y  as initial velocity ,final velocity and acceleration in Y direction. Consider both the accelerations constant. In time t object have 'x' and 'y' displacem...
