For A Certain Optical Medium The Speed Of Light Varies From A Low Value Of 1 90 X 108 M S For Violet Light To A High Val 1 (57.54 KiB) Viewed 25 times
For a certain optical medium the speed of light varies from a low value of 1.90 x 108 m/s for violet light to a high value of 2.02 x 108 m/s for red light. Calculate the range of the index of refraction n of the material for visible light. nviolet = nred= A white light is incident on the medium from air, making an angle of 32.0° with the normal. Compare the angles of refraction for violet light and red light. violet = Øred = Compare the angles of refraction for violet light and red light when the incident angle is 58.0°.
Light that has a 650-nm wavelength is incident upon two narrow slits that are separated by 0.400 mm. An interference pattern from the slits is projected onto a screen that is 3.00 m away. What is the separation distance Dы on the screen of the first bright fringe from the central bright fringe? Dbl 1 = Dd2 What is the separation distance Da2 on the screen of the second dark fringe from the central bright fringe? 4.87 ×10-3 = 7.305 ×10-6 Incorrect m m
