Question

ACROSS 1. Type of interference in dark fringes of double slit pattern. 1. SI unit for power of lens. 4. This scientist claimed light is not a wave, otherwise diftraction would create a bright spot in the shadow of a disc. 3. Polished mirror gives this type of reflection (opposte of diffuse) 6. Study of the dispersed spectrum of light. DOWN 2. This instrument generated the null result 5. This scientist derived the special theory of relativity 8. This is often used in place of a large diameter glass lens in large optics use phenomena of total internal reflection 7. These sunglasses significantly reduce glare. 10. Image through which light rays do not pass 11. A person who has trouble seeing faraway objects 12. This muscle controls the shape of the lens in the eye. 14. This type mirror has a focal length of infinity (and is commonly found on the wall above the bathroom sink) 15. Name of the scientist who derived n,sin8, n,sine 18. This parameter is unitless in the SI system of units. 21. The index of refraction ini 24. lmage is larger than object (m> 1) 25. A blind spot in your vision is produced by your optic 26, A good telescope has a large dameter lens 28. An average diameter of the human eye is mm 13. A real, inverted, and reduced image is formed in this instrument. 16. This scientist interpreted the results of his double slit experiment to mean that light was a wave 17 Formulated the theory that light was made of particles 19.This has an index of refraction of n =242 20. Theof an average person with good eyesight is 25cm 22. Michelson's colleague in the null result experiment 23. Above this angle, light rays will experience total internal reflection 27.
