Electrons are ejected from a metallic surface with speeds ranging up to 4.1 × 105 m/s when light with a wavelength of 630nm is used. What is the cutoff frequency for this surface? Express your answer in terms of 1014 Hz and round it to the nearest hundredth. For example, if you get 1.234 x 1014 Hz, you type in 1.23. (Hint: you should first calculate the work function of the surface.) Use h=6.626x1034 Js; c=3 x108 m/s. ; me=9.11x10-31kg Js; c=3 x108 m/s. ; me=9.11x1031kg
Q.1 Find the dispersion relation for electrostatic electron waves propagating at an arbitrary angle 0 relative to B,. Hint: Choose the x axis so that k and E lie in the x - z plane. Then Ex = E,sin0, E, = E,cos0,Ey = 0 and similarly, for k. Solve the equations of motion and continuity and Poisson's equation in the usual way with no uniform and v, = Eo = 0.
Problem 9: For a Gaussian laser beam in air with a 0.5mm waist radius and X=850nm, a. Find the (far field) diffraction half angle and the beam waist w(z) at z=50m b. If the laser emits 5mW, what is the peak irradiance at z=50m? c. What near field beam waist radius is required to limit the diffracted beam diameter to 1cm at 50m? What detector diameter is needed to encircle (detect) 50% of the power?
