For statements 39-40 below, write true or rewrite the italicized part to make the statement true 43. Two slits are 1.95 x 10 m apart. A red laser beam falls on the slits. A first-order bright band appears 4.42 x 10"2 m from the central bright band. The screen is 1.25 m from the slits. What is 39. The higher the index of refraction is, the faster is the speed of light in the substance. the wavelength of the light? 39. 40. Chromatic aberration can be reduced by joining together a convex lens and a concave lens. 40. 44. A monochromatic light with a wavelength of 570 nm passes through two slits that are 41. For most practical purposes, the index of refraction of air is 1.90 x 10-5 m apart and are 0.800 m from the screen. In millimeters, what is the distance between infinite the first-order bright band and the central bright band? 1.00 equal to that of the other medium involved 42. When light travels from one medium into a medium with a lower index of refraction,_ 45. The same monochromatic light with a wavelength of 570 nm passes through a single slit with a width of 0.0900 mm. The distance from the slit to the screen remains at 0.800 m. In the speed of light increases millimeters, what is the width of the central bright band ? the angle of refraction is smaller than the angle of incidence the refracted light bends toward the normal the angle of incidence equals the angle of refraction
