Year 8: refraction

Refraction refers to the

• bending of light through different mediums

• bending of light at exact angles of a surface of a mirror

The measure of how much a substance bends light is described as the

• Refractive index

• Reflective index

• Index laws

• Defractive index

Mediums (substances) with a high refractive index ("more dense")

• bend light more

• Bend light less

Mediums with a low refractive index (less dense)

• bend light more

• Bend light less

Light travels faster through mediums (substances) with a

• low refractive index ("less dense")

• high refractive index ("more dense")

Light travels slower through mediums with a

• low refractive index ("less dense")

• high refractive index ("more dense")
