Question Details Wolfl 30513 742800 The mirriors in Fig3019 make a 60 angle A light ray enters parallel to the symmetry axis as shown Figure 301 a How many reflections does it make ri 39l I 3W 3 b Where and in what direction does it exit the mirror system off the second mirror parallel to the incident ray off the second mirror at an angle of 60 off the first mirror and normal to it off the first mirror at an angle of 60 7 off the first mirror along and in the opposite direction to the incident ray Question Details Wolfl 30E19 754402 A light ray propagates in a transparent material at 112 to the normal to the surface When it emerges into the surrounding air it makes a igiangle with the normal What is the refractive index of the material Question Details Wolfl 30E17 754468 Information in a compact disc is stored in quotpitsquot whose depth is essentially one fourth of the wavelength of the laser light used to quotreadquot the information That wavelength is roughly 779 nm in air but the wavelength on which the pit depth is based is measured irLthie 157 plastic that makes up most of the disc Find the pit depth Question Details Wolfl 30P33 742881 A meter stick lies on the bottom of the rectangular tank in Fig 3021 h 35 cm with its zero mark at the left edge of the tank You look into the long dimension of the tank at an angle of r 43 with your line of sight just grazing the top edge of the tank as shown Figure 3021 What mark on the meter stick do you see when the tank is a empty c full of water Question Details Wolfl 30P38 742715 A light ray is propagating in a crystal where its wavelength is 592 nm It strikes the interior surface of the crystal with an incidence angle of 36 and emerges into the surrounding air at 72 to the surface normal a Find the light39s equency C b Find its wavelength in air 1 l7 1 m Question Details Wolfl 30P36 754138 You39re standing i 1 m horizontally from the edge of a 36 m deep lake with your eyes 20 m above the water surface A diver holding a flashlight at the lake bottom shines the light so you can see it If the light in the water makes a 42 angle with the vertical at what horizontal distance is the diver from the edge of the lake 1 Question Details Wolfl 30P43 754463 What is the speed of ht in a material for which the critical angle at an interface with air is 43 Question Details Wolfl 30P44 742911 The prism of Fig 3011 has n 1274 When it is immersed in a liquid a beam incident as shown in the figure ceases to undergo totalwgflgction What is the minimum value for the liquid39s refractive index I use
