1 Check yourself pg 62-63

2 1 Real sun Apparent sun

3 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)

4 n air = n glass = 1.5 The normal is RED The refracted ray is BLUE

5 6 Which substance has a higher index of refraction? Is the refracted ray going to bend towards or away from the normal? 40° 50°

6 9. The speed of light in a transparent gel is 2.20 x 10 8 m/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 10 8 m/s Incidence Angle = 30 ° Angle of Refraction = ? Looking for: Need n

Givens: v = 2.20 x 10 8 m/s Incidence Angle = 30 ° Angle of Refraction = ? Looking for: 1 st substance is air…. n 1 = 1.00 Assume n 2 = 1.36
