'I. Part of a pencil that is placed in a glass of water appeals bent in rela tion to the part. of the pencil that extends out of the water. What is this phenomenon called? a. interference c. diffraction b, refraction d, reflection Refraction is the bending of a wave disturbance as it passes at an angle from one into another. a. 1355 c. area b. medium cl. boundary The of light can change when light is refracted because the medium changes . a. frequency c. speed b. color cl. transparency _ light isnot refracted when it is a. traveling from air into a glass of water at an angle of 35 to the normal . b, traveling from water into air at an angle of 35" to the normal - c. strilcing a wood surface at an angle of TE- d, traveling from air into a diamond at an angle of 45'\"- When light passes at an angle to the normal from one material into another material in which its speed is higher, a. it is bent toward the normal to the surface- b. it always lies along the normal to the surface . c. it is unaffected . d. it is bent away from the normal to the surface- _ When light passes at an angle to the normal from one material into another material in which its speed is lower1 a. it is bent toward the normal to the surface. b, it always lies along the normal to the surface . c_ it is unaffected . d, it is bent away from the normal to the surface. I What type of image is fonned when rays of light actually intersect? a. real c. curved b. viual d, projected
