Question 2

___ propagates in a straight line

Answer 2

propagates

Question 3

As you will see, the direction of light propagation changes abruptly when light encounters a ___
surface. T

Answer 3

reflective

Question 4

The direction also changes abruptly when light passes across a boundary between two different media
of propagation, such as between air and acrylic, or between glass and water. In this case, the change of
direction is called

Answer 4

refraction

Question 5

law of refraction (snell’s law) formula

Answer 5

n1 sin θ1 = n2 sin θ2

Question 6

depend on the two media through
which the light is passing. T

Answer 6

indices of refraction

Question 7

The angles θ1
and θ2 in snells law are

Answer 7

are the angles that the ray of light makes with the normal to
the boundary between the two media.

Question 8

study the angle of reflection and angle of incidence in experiment for refraction

Answer 8

+1
