Light at two different wavelengths, 750nm and 450nm, is shone through the same single slit at the same time. The two diffraction patterns are lined up to have a common central bright fringe, which appears on the screen 1.50m from the slit. The shortest distance from the centre of where dark fringes from each pattern overlap is 6.75cm. Determine the slit's width.
Coherent ligh of a wavelength 500nm passes through a narrow slit. In the single-slit diffraction pattern observed on a screen that is 4.0m from the slit, what will the width of the central maximum be
There is an isolated point charge of q = +15 ?C. Using a test charge of q0 = +0.80 ?C, determine the E-field at point P which is 0.20 m away
To get the top spinning, its string is pulled with a tension of 0.30. Explain how long does it take for the top to complete the first five revolutions? The string is long enough that it is wrapped around the top more than five turns.
