Reflection & Refraction

2. Reflection & Refraction
Reflection is when a wave reaches a boundary between to media, some or all of the wave bounces back.

3. Reflection & Refraction
When light is incident and reflects of a mirror, both the incident angle and reflected angle are equal. This is the Law of Reflection.
(Angle of Incidence = Angle of Reflection)

4. Reflection & Refraction
Mirrors
Any object placed in front of a plane (flat) mirror is known as a object.
The image that appears to originate from a point behind the mirror is called a virtual image, because light does not actually start there.

5. Reflection & Refraction
Your eye cannot tell the difference between a real object and a
virtual image.

6. Reflection & Refraction
In all plane mirrors, your distance from the mirror and the virtual image distance are equal. Also image size is the same as object size.

7. Reflection & Refraction
Diffuse Reflection
Diffuse Reflection is when light are reflected on a rough surface, light is reflected in many directions.

8. Reflection & Refraction
Paper is a good example of a diffuse reflector. If paper were not, you could only read the paper in one specific direction.

9. Reflection & Refraction
Like light, sound will reflect. A echo is reflected sound. Many reflections of sound are called reverberations.
