Refraction

 

A student placed a pencil in a cup of water. The pencil appears broken because light

• reflects the pencil on the water's surface.

• slows down when it passes through water

• Because it is broken

• always travels in a straight line.

When light goes from a less dense to a more dense medium

• it is bent towards the normal.

• It bends away from the normal

• It doesn't bend

• It floats

Light has the LOWEST speed in which medium? Numbers are from Refractive Index

• flint glass =1.70

• barium glass =1.60

• water =1.33

• diamond =2.45

Glass has a _____________ level of refraction than air.

• Equal

• Lesser

• Greater

• Level 10 Town Hall

Light has the highest speed in which medium?

• flint glass =1.70

• barium glass =1.60

• crown glass =1.523

• water =1.33

. 

Based on the image, which medium has a higher density?

• Can't be determined

• Medium 1

• Medium 2

• What???

• Reflection

• Refraction

• Fracture

• Water Bending
