Light from a laser strikes a diffraction grating that has 5 302 grooves per centimeter. The central and first-order principal maxima are separated by 0.488 m on a wall 1.90 m from the grating. Determine the wavelength of the laser light. (In this problem, assume that the light is incident normally on the gratings.) nm

Coherent light with wavelength 600 nm passes through two very narrow slits and the interference pattern is displayed on a screen 0.80 m from the slits. 13 bright fringes are observed with a spacing of 4.00 cm between the center of the outside fringes. What is the spacing between the two slits? (Give your answer in micrometers.) Ive submitted this question multiple times and it has been incorrect on every occasion. The answer is absolutely not 1.56mm.

(a) An air wedge is formed between two glass plates separated at one edge by a very fine wire of circular cross section as shown in the figure below. When the wedge is illuminated from above by 600 nm light and viewed from above, 30 dark fringes are observed. Calculate the diameter d of the wire (in um). μm (b) What If? How many dark fringes will be observed if the gap between the glass plates is filled with water? dark fringes Need Help? Read It Master It
