Properties of Light

It is when a wave strikes an object and bounces off it.

• Reflection

• Refraction

• Diffraction

• Interference

Bending of waves when passing through another medium.

• Reflection

• Refraction

• Diffraction

• Interference

Bending of waves on a barrier.

• Reflection

• Refraction

• Diffraction

• Interference

When two waves meet, they have an effect on each other.

• Reflection

• Refraction

• Diffraction

• Interference

The angle of incidence equals the angle of reflection.

• Law of Reflection

• Law of Refraction

when all light is reflected back into the denser medium.

• Total Internal Reflection

• Total External Reflection

• Kind of total reflection

refracted ray bends toward the normal

• slower (more dense)

• faster (less dense)

refracted ray bends away the normal

• slower (more dense)

• faster (less dense)
