Coherent light that contains two wavelengths 660nm and 470nm passes through two narrow slits with a separation of 0.340mm and an interference pattern is obeserved on a screen which is a distance 5.00m from the slits.

What is the disatnce on the screen between the first order bright fringe for each wavelength

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
