### Check yourself pg 62-63

Apparent sun

Real sun

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

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 = ?
