Reflection, Refraction, Diffraction, Interference

What is Refraction?

• change in direction of waves when waves travel through water

• When waves bounces off of an object

• when two waves superpose to form a resultant wave

• beam of light is spread out when passing through an aperture

What is Reflection?

• change in direction of waves when waves travel through water

• when two waves superpose to form a resultant wave

• When waves bounces off of an object

• beam of light is spread out when passing through an aperture

What is Diffraction?

• change in direction of waves when waves travel through water

• beam of light is spread out when passing through an aperture

• when waves spread out as they travel around obstacles

• when two waves superpose to form a resultant wave

What is Interference of waves?

• change in direction of waves when waves travel through water

• When waves bounces off of an object

• beam of light is spread out when passing through an aperture

• when two waves superpose to form a resultant wave
