### Step-by-Step Solution: 1. **Introduction to the Experiment**: - In this experiment, moving electrons are directed towards a thin graphite film. The electrons are accelerated in an electron gun to a high potential, typically between 3500 volts and 5000 volts. 2. **Interaction with Graphite**: - When the high-energy electrons strike the thin graphite film, they interact with the carbon atoms present in the graphite. ...

(i) Find the de Broglie wavelength of electrons moving with a speed of 7xx10^(6)ms^(-1) (ii) Describe in brief what is observed when moving electrons are allowed to fall on a thin graphite film and the emergent beam fall on a fluorescent screen.

Following experiment was performed by J.J. Thomson in order to measure ratio of charge e and mass m of electron. Electrons emitted from a hot filament are accelerated by a potential difference V. As the electrons pass through deflecting plates, they encounter both electric and magnetic fields. the entire region in which electrons leave the plates they enters a field free region that extends to fluorescent screen. The entire region in which electrons travel is evacuated. Firstly, electric and magnetic fields were made zero and position of undeflected electron beam on the screen was noted. The electric field was turned on and resulting deflection was noted. Deflection is given by d_(1) = (eEL^(2))/(2mV^(2)) where L = length of deflecting plate and v = speed of electron. In second part of experiment, magnetic field was adjusted so as to exactly cancel the electric force leaving the electron beam undeflected. This gives eE = evB. Using expression for d_(1) we can find out (e)/(m) = (2d_(1)E)/(B^(2)L^(2)) If the electron is deflected downward when only electric field is turned on, in what direction do the electric and magnetic fields point in second part of experiment

A YDSE is performed in a medium of refractive index 4 // 3 , A light of 600 nm wavelength is falling on the slits having 0.45 nm separation . The lower slit S_(2) is covered b a thin glass plate of thickness 10.4 mm and refractive index 1.5. The interference pattern is observed on a screen placed 1.5 m from the slits as shown in figure.
