- Wavelength of visible light: Find the range of wavelengths (in vacuum) for visible light in the frequency range between 4e14 Hz (red) and 8e14 Hz (violet). Express your answer in nanometers. Answer (red light 749 nm; violet 375 nm)
- Young's 2-slit experiment: Red light (713 nm in vacuum) is used in a Young's 2 slit experiment with slits separated by 120 microns. The screen is 2.75 meters from the slit plate. Find the distance, y, on the screen between the central bright fringe and the third order (n = 3) bright fringe. (answer: 4.9 cm)
