Question 2 Not complete Points out of 1.00 Flag question In the Figure a wave front of light is hitting a smooth surface. Please answer the following questions about the Figure above. Why does the wave front change directions at the surface? In what preferred direction are the transmitted waves bent? Is the speed of the wave before it enters the media related to the speed in the Choose... Choose. Choose... Yes via Snell's Law which relates the speeds of the the waves in both medias. The difference in velocity of the waves causes the wave to bend. They are bent toward the normal (perpendicular) to the surface. media? Check

Explanation / Answer

1) wave front change direction due to difference in velocity of the waves. This difference in velocity occurs due to material density variation.

2) they are bent towards the normal (perpendicular ) to the surface

3) snell's law relates the speed in differenr mediums. In different mediums, the speed will vary depending on the value of refractive index.
