Two nearly equal wavelengths of light are incident on an N-slit grating. The two wavelengths are not resolvable. When N is increased they become resolvable. This is because: A. more light gets through the grating B. the lines get more intense C. the entire pattern spreads out D. there are more orders present E. the lines become more narrow
Homework Answers
so when we increase the N(number of slits) resolving power of the slit increases which leads to spreading of pattern on to the screen.so due to spreading of pattern the pattern becomes more visible.

An intense monochromatic light incident on a diffraction grating with slit spacing d is causing an increase of the grating temperature. How should the frequency of the light be changed so that the position of bright fringes does not change. (Consider that the thermal expansion of the diffraction grating does not damage the slits.) Select one: a. f should be increased. b. f has no effect on the position of the bright fringes. c. f should be decreased. d. f...

The spectrum of light from heated up Helium gas has only a few wavelengths present. These are known as spectral lines. It includes a strong yellow line with a wavelength in a vacuum of 587.5 nm and a red line at 667.8 nm. What are the angular separations (in degrees) between these two spectral lines for all visible orders obtained with a diffraction grating that has 7350 grooves/cm? (In this problem assume that the light is incident normally on the...

Plane coherent light waves with wavelength 565 nm are incident on two narrow parallel slits positioned a distance d = 1 mm apart in a plane parallel to the incoming wavefronts. The interference pattern is observed on a screen parallel to the original wavefronts at 1 m from the two slits. One of the slits is covered on the illuminated side by a glass slide of 0.1 mm thickness with refractive index 1.5. a/ What is the phase difference ∆φ...

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...
