In a double-slit experiment, two coherent wavelengths of light, 425 nm and 510 nm, illuminate the slits of separation is 1.75 mm and a screen located 5 m away from the double-slit system, the bright fringes of diffraction patterns from both light sources coincide at several locations.
What is the deflection distance from the central maximum for the first coincidence?
Copper at 20C has a resistivity of 1.72x10^-8 ohm-m. A potential difference of 2.0V is applied to a 1.00m long copper wire of radius 0.200mm. Find the resistance of the wire
Light of wavelength 590 nm and light of unknown wavelength both pass during two narrow slits 0.600 mm apart. The screen is 1.70 m away. On the screen the second-order bright fringe of the unknown-wavelength light is 1.33 mm closer to the central maxi..
