Check yourself pg 62-63. 1. Apparent sun. Real sun. Check yourself. Light bends towards the normal when moves into a more optically dense substance. Low to high towards Fast to slow towards (remember: FST ). n air = 1.000 n glass = 1.5. The normal is RED.

Check yourself Light bends towards the normal when moves into a more optically dense substance Low to high towards Fast to slow towards (remember: FST)
nair = 1.000 nglass = 1.5 The normal is RED The refracted ray is BLUE
6 Which substance has a higher index of refraction? Is the refracted ray going to bend towards or away from the normal? 40° 50° 50°
9. The speed of light in a transparent gel is 2.20 x 108m/s. If the angle of incidence of a beam of light directed at the surface of the gel is 30°. what is the angle of refraction in the gel? Givens: v = 2.20 x 108 m/s Incidence Angle = 30° Looking for: Angle of Refraction = ? Need n
9. The speed of light in a transparent gel is 2.20 x 108m/s. If the angle of incidence of a beam of light directed at the surface of the gel is 30°. what is the angle of refraction in the gel? Assume Givens: 1st substance is air…. n1 = 1.00 v = 2.20 x 108 m/s Incidence Angle = 30° n2 = 1.36 Looking for: Angle of Refraction = ?
