Compton Scattering

 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:

                    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) ...

Speed, Velocity and Acceleration (Kinematics - 1)

Rest and Motion: We can say if a body does not change it's position with time, it is at rest. And if a body changes it's position with time, it is said to be moving. But, how do we know that a particle is in motion or not ? To find the position of the particle we need a frame of reference. Let's fix the frame of reference as the three mutually perpendicular axes X, Y and Z. Assume that particle has co-ordinates (x, y, z) at any instant. After a while, if all co-ordinates of the particle remains same with time that means particle is at rest with respect to that frame of reference. And if one or more co-ordinates change with time, it is called as moving particle. There is not any restriction of a choice of a frame of reference. We can choose a frame of reference according to our convenience.  For simplicity assume yourself at rest at the frame of reference. For example a bus is moving with a speed. First, I take bus as the reference that means I should have put m...
