Document Summary
Light passes through a 10- m-wide slit and is viewed on a screen 1 m behind the slit. If the width of the slit is narrowed, the band of light on the screen will . Blue light of wavelength 450 nm passes through a diffraction grating with a slit spacing of 0. 001 mm and makes a diffraction pattern on the wall. How many bright fringes will be seen? dsin m = m sin m = 1. 450 x 10 9 m = m = 2. 2. The index of refraction n = speed of light in a vacuum/speed of light in the material = c/v v = c/n. Changing speed makes light bend n1sin 1 = n2sin 2. A 4. 0-m-wide swimming pool is filled to the top. The bottom of the pool becomes completely shaded in the afternoon when the sun is 20 above the horizon. How deep is the pool? n1sin 1 = n2sin 2 (1)sin(70 ) = (1. 33)sin 2.
