The speed of light through a material is measured to be 2.5x108 m/s. What is the dielectric constant of this material? ii) 1.20 iii) 1.36 iv) 1.44 Monochromatic light impinges two slits that are separated by 8 μm. If the third (m=3) dark fringe is observed at angle 0 = 5.15° from the direction of the incident beam of light, what is the wavelength of the light? i) 205 nm ii) 339 nm iv) 546 nm A coin lies at the bottom of a 20 cm tall glass that is filled to the top with cooking oil (n = 1.47). Looking from above (n = 1.00), how deep does the coin appear? i) 12.2 cm ii) 13.6 cm iii) 22.8 cm iv) 29.4 cm If light from the coin in the previous question strikes the oil/air interface at an incident angle of 10°, at what angle do you need to have put your eyes to see it? i) 6.8° ii) 8.2° iii) 11.3° iv) 14.8° i) 1.11 iii) 479 nm What is the focal length of a double convex lens that has radii of curvature of 20 mm on both sides and is made of glass (n = 1.52)? i) -13.1 mm ii) +17.8 mm iii) -19.2 mm iv) +21.2 mm
