How can the diagram be used to make a model?

• The diagram can be used to make a model of waves reflecting in a straight line.

• The diagram can be used to make a model of light being absorbed as it enters a mirror.

• The diagram can be used to make a model of waves speeding up as they reflect off a shiny surface.

• The diagram can be used to make a model of light bending in a straight line.

Which two statements are supported by evidence in the diagram?

• Glasses can bend light so that light reaches the retina after it passes through the lens.
