Q6) Give a commonly accepted range in nm of visible wavelengths of light (1 mark)
For the following questions, assume the wavelengths of visible light range from 380 nm to 760 nm in a vacuum. (a) What is the smallest separation (in nm) between two slits that will produce a seventh-order maximum for any visible light? nm (b) What is the smallest separation (in nm) between two slits that will produce a seventh-order maximum for all visible light? nm
A light source emits visible light of two wavelengths: 600 nm and al-450 nm). The source is used in a double-slit interference experiment in which L-1.5 m and d-0.030 mm. Find the separation distance between the 3 -order bright fringes for the two wavelengths.) (Show step by step solution)
2. Ultraviolet light emitted by the sun has wavelengths between 200 nm and 400 nm. Visible light is between 400 nm and 700 nm. Will a photon of ultraviolet light from the sun break the chemical bond in an oxygen molecule, which has an energy of 494 k.J/mol? Will a photon of visible light break this bond?
For what visible wavelengths (400 to 700 nm) will the observer see the brightest light, owing to constructive interference? Two light sources can be adjusted to emit monochromatic light of any visible wavelength. The two sources are coherent, 2.04 pm apart, and in line with an observer, so that one source is 2.04 um farther from the observer than the other Enter your answers numerically in ascending order separated by a comma(s). 1 = 408.510.880 nm Submit Previous Answers Correct...
8. Visible light has wavelengths between about 1 = 400nm on the violet end of the spectrum to about l = 700nm on the red end. An anti-reflective coating with index ne = 1.2 forms a thin film on the surface of a glass lens with index n, = 1.5. (a) For a wavelength in middle of the visible-wavelength range (which appears green), find the minimum thickness of the coating for dark reflections of light entering the lens from the...

Check all that apply. 430 nm 660 nm 530 nm 400 450 500 550 600 Wavelength (nm) 650 700 wavelength (nm) In a laboratory experiment, you take three plants and put them each under a lamp that mimics sunlight. You have three colored light filters that fit over each of the lamps: a...
An electric current through hydrogen gas produces several distinct wavelengths of visible light. What are the wavelengths of the hydrogen spectrum, if they form first-order maxima at angles of 24.2° , 25.7°, 29.1°, and 41.0° when projected on a diffraction grating having 10,000 lines per centimeter? Answer: nm for 24.2° Answer: nm for 25.7° Answer: nm for 29.1° Answer: nm for 41.0° At what angle is the first minimum for 550- nm light falling on a single slit of width...
